g-cpan crashes under Perl 5.18. The problem is that Perl 5.18 changes the way the qw() quoting construct works, so you can no longer write code like "foreach $x qw(a b c)". You now have to use "foreach $x (qw(a b c))" instead Both g-cpan and the Gentoo::CPAN module need a few instances of this changed. Reproducible: Always Steps to Reproduce: 1. run g-cpan (with any arguments, or none. It doesn't matter.)

Compilation failed in require. BEGIN failed--compilation aborted. Expected Results: It ought to work the same way it always did. Gentoo::CPAN needs two changes: the use of qw() needs to be changed to (qw()) on lines 324 and 386. g-cpan needs a similar change on line 716. I can make a proper diff to feed into patch if you really need it.

Which g-cpan version is this?
Actually, this should already be fixed in ~arch g-cpan... (Technically this is a dupe of bug 424657) Arches please stabilize app-portage/g-cpan-0.16.5 Target: all stable arches
Stable on alpha.
