While testing CPANPLUS on my bleadperl test directory, I ran into the following problem. I built and installed bleadperl into a dedicated directory. I then ran cpanp5.9.5 and told it to t CPANPLUS It warned me: Since CPANPLUS 0.050 has a few prerequisites that are not core perl (yet), they are bundled with the distribution for boot- strapping purposes. You should install these prerequisites before continueing to install CPANPLUS. You can use the bootstrapped CPANPLUS to do this for you with the following commands: /home/doughera/my/perl/bin/perl5.9.5 bin/cpanp-boxed -s selfupdate dependencies /home/doughera/my/perl/bin/perl5.9.5 bin/cpanp-boxed -s selfupdate enabled_features Running either of those commands produces the unhelpful message: [ERROR] No such plugin command Since I don't know what is missing, I'm stuck on what to do next. -- Andy Dougherty doughera@lafayette.edu

This is *very* odd and according to the code path, shouldn't happen. Plugin commands are triggered by using /foo commands, rather than -foo commands, so i can recreate this diagnostic by doing: /usr/local/bin/perl bin/cpanp-boxed /s selfupdate dependencies --dryrun Note the /s Are you sure you're using -s, and not /s? If so, you've run into the weirdest bug i've ever seen.

Yes. I cut-and-pasted it and also tried typing it manually just to be sure. Oh, wait a minute. I was typing this at the CPANPLUS shell. I have to quit CPANPLUS, change to the build directory hidden under ~/.cpanplus, and then run the command from my command-line shell there. Oh. I see. That wasn't obvious to me. Sorry about that. It wasn't clear to me that I had do that. Anyway, perhaps the whole message can be skipped if the prerequisites are already there? -- Andy Dougherty doughera@lafayette.edu

No you don't. Not at all. The message you pasted comes from the ***Makefile.PL***. You aren't in the CPANPLUS shell at this time. You dont have to chdir to any hidden directory anywhere. It's all from your *current directory*. No magic involved. When you *run* 'perl Makefile.PL' it sells you the following: ### PLEASE NOTE ################################################### Since CPANPLUS 0.050 has a few prerequisites that are not core perl (yet), they are bundled with the distribution for boot- strapping purposes. You should install these prerequisites before continueing to install CPANPLUS.

Sorry, my original statement is correct. I was in the CPANPLUS shell. I got this message by running t CPANPLUS while in the CPANPLUS shell. I saw the exact message you quote below, but I was in the CPANPLUS shell. (Presumably, CPANPLUS runs 'perl Makefile.PL' to build the distribution.) Show quoted text

right... so it recursed... i'm not sure how to clarify that output seen when running a distributions 'perl Makefile.PL' isn't input you can give to a CPAN client like CPAN.pm or CPANPLUS. Again, suggestions welcome. Also note that when you run 't CPANPLUS', dependencies are written out in the generated Makefile, and CPANPLUS (the parent process) will just take care of them, as it states in the 'Makefile.PL' output. So no action is needed on your part. -- Jos Boumans 'Real programmers use "cat > a.out"'

When you're in the CPANPLUS shell, it's not necessarily obvious what is generating the output. It is to you, since you wrote it, but it's not obvious to the end user. I'd suggest the following. It removes the reference to the bootstrapped CPANPLUS (which is probably what suggested to me that I could do this within the CPANPLUS shell), mentions the build directory explicitly, and puts the conventional '$' in front of the command to emphasize that it's a shell command. (This matches the style in the preceeding note about configuration.) I think these cues would have been sufficient for me. While I was at it, I took out the obsolete 0.50 version reference, rephrased the 'package manager' comment, and skipped printing out the message for versions of perl new enough that it would be irrelevant anyway. I think this should cover it. diff -r -u CPANPLUS-0.80/Makefile.PL CPANPLUS-0.80-patched/Makefile.PL --- CPANPLUS-0.80/Makefile.PL 2007-05-16 18:43:15.000000000 -0400 +++ CPANPLUS-0.80-patched/Makefile.PL 2007-07-03 13:16:11.000000000 -0400 @@ -119,21 +119,22 @@ } ### mention our prereqs +if ($] < 5.009005) { print loc(" ### PLEASE NOTE ################################################### -Since CPANPLUS 0.050 has a few prerequisites that are not core -perl (yet), they are bundled with the distribution for boot- -strapping purposes. - -You should install these prerequisites before continueing to -install CPANPLUS.
