This can occur when the source files fetched from your prefered mirrors (02packages.gz and friends) are corrupted during the download. Refetching them with 'x --update_source' might make the issue go away, or alternately changing your mirrors (see 's mirrors' for your mirror config). If the issue persists, let me know. Please include the .gz files found in your ~/.cpanplus directory in that case. Thanks, Jos

Refetching with 'x --update_source' did not resolve the problem. FWIW, my primary mirror is ftp://ftp.cpan.org/pub/CPAN. Files attached.

Hmm, I'm afraid I can not reproduce the problem with these sourcefiles, they look clean to me. So, let's try some more diagnostics. First, please enable verbose mode as follows: s conf verbose 1 and we'll also disable the use of storable for this test: s conf storable 0 If you dont want to retype these commands every time you restart cpanp, save them: s save Next, remove any .stored files in your .cpanplus dir: rm ~/.cpanplus/*.stored Now let's try some scenarios. Whenever the error occurs, please mark it down, and quit cpanp before trying the next command. Here's a list with commands to try: x m Acme::Bleach o f Acme::Bleach a DCONWAY r Acme::Bleach If they all present the error, it's definitely the sourcefiles at work or the parsing of them (although this is the first report i've seen for 0.076 or any other release..). If it's only some, the error may be more subtle and we'll have to continue investigating. Thanks for your time, Jos

Since all the other commands worked just fine, the only other part of the 'o' command that contains an eval is finding out the version of an installed pacakge. I'll have to give an easy debugging strategy some thought... stay tuned :) -- Jos

I've looked at the problem a bit more and I hope I found a way now to narrow it down based on your previous feedback. The problem *seems* to come from the VERSION declarations found in one or more modules. The module that does this parsing got upgraded a few weeks ago. If you're not running the most recent version, perhaps upgrading to it would solve your issue. The newest release is Module::Load::Conditional 0.16. If that does the trick, please let me know and I'll up the minimum requirement for it. In case that doesn't work, I've pasted a test script below that should give us more output about the actual failure in the hope to track down the root of the issue. If you could provide me with the output of that script that would be wonderful. Also, the script writes an autobundle file to disk (last line of the output). If you could attach this one in your next reply, that'd be much appreciated. Thanks for your patience, -- Jos __END__ BEGIN { require Carp; $Carp::MaxArgLen = 0; $Carp::MaxEvalLen = 0; $Carp::MaxArgNums = 0; *CORE::GLOBAL::die = sub { Carp::confess( @_ ); } } use strict; use Module::Load::Conditional; print "M::L::C->VERSION: " .
