Which release version of Strawberry? Are you using a minicpan? If not, which, CPAN mirror are you using and can you confirm that it contains Perl6-Signatures-0.03? -- David

I have tried 1. 'reload index' 2. adding 'ftp://ftp.funet.fi/pub/languages/perl/CPAN/' as first mirror no change. 3. turning use_sqlite off, and it works (started upgrading dependency). Turning on - doesn't. Upgrading CPAN::SQLite to latest version didn't solved problem. -- Alexandr Ciornii, http://chorny.net

I'm experiencing the same problem on armv5tejl-linux, in both 5.8.8 and 5.10 with recent CPAN::SQLite 0.196 and CPAN 1.92_63 (1.93 failed for some reasons on this platform). You can get cpandb.sql and Metadata files from http://trouchelle.com/tmp/CPAN-req-problem-datafiles.zip (6264k), but I suppose it can be reproduced quite easy. -- Serguei Trouchelle

I tried tracing through the dependencies, but couldn't pinpoint where it failed to resolve things. Just to clarify - when you turned use_sqlite off, which dependency (or dependencies) was it that then get resolved? Were these missing dependencies new to your system, or were they packages that were already installed that required upgrading to a higher version? Thanks. -- best regards, Randy

I believe I found the source of this problem, which arises in the case when a version of a module is present but which is too old as specified in the prerequisites. I've attached a patch to CPAN::Distribution which fixes this for me.

diff --git a/lib/CPAN/Distribution.pm b/lib/CPAN/Distribution.pm index 68a9096..3f4d01d 100644 --- a/lib/CPAN/Distribution.pm +++ b/lib/CPAN/Distribution.pm @@ -2515,6 +2515,10 @@ sub unsat_prereq { $available_version = $]; $available_file = CPAN::find_perl(); } else { + if (CPAN::_sqlite_running()) { + CPAN::Index->reload; + $CPAN::SQLite->search("CPAN::Module",$need_module); + } $nmo = $CPAN::META->instance("CPAN::Module",$need_module); next if $nmo->uptodate; $available_file = $nmo->available_file;
