I've tried to install DBD::CSV using g-cpan. After working around some initial issues described here: http://forums.gentoo.org/viewtopic-t-822042-highlight-.html g-cpan failed to fetch the source tarball. The URL that portage tried to fetch was invalid - the filename should end with a .tgz instead of .tar.gz for this particular module. The URL was invalid because perl-module.eclass assumed it to be 'tar.gz' in absence of MODULE_A set in the ebuild generated by g-cpan. I have developed a patch for g-cpan that fixes this problem - it checks if the tarball extension for the CPAN module is '.tgz' - if yes it adds MODULE_A=${P}.tgz to the generated ebuild. The patch is attached. I'm not sure however if this is the most clean way to fix this - maybe a better solution would be for perl-modules.eclass to use a MODULE_EXTENSION variable to generate the MODULE_A instead of using a hardcoded 'tar.gz' ?

Bug report QA messages: * Please use full package qualifiers (e.g. "sys-apps/portage", not just "portage") in bug report titles, at the beginning ideally, in the future. Thank you!
Implemented a variant of your idea in g-cpan now. Committed to git, will be in next release.
