Fails on packages there is mismatching between module & package versions

[jmfernandez]

Meanwhile I was trying to generate an ebuild for OWL::Simple::Parser module, the digestion phase failed because g-cpan used as version number the one from the module (1.01) instead of the one from the whole Perl package (0.51) which contains it, as you can see at http://cpansearch.perl.org/src/TOMASZ/OWL-Simple-0.51/META.json

So, all these commands generate wrong ebuilds:

• g-cpan -g OWL::Simple::Parser -> FAILS (misuses version 1.01 instead of 0.51)
• g-cpan -g OWL::Simple::OBOWriter -> FAILS (misuses version 0.06 instead of 0.51)
• g-cpan -g OWL-Simple -> FAILS (due the package does not contain a OWL::Simple module)

I tested this with g-cpan 0.16.6 and master version, with the same results.

I have also realized that the generated ebuild contains a wrong dependency on dev-lang/io instead of perl-core/IO or virtual/perl-IO

@jmfernandez please test current live version,
is it ok for you now?
emerge =app-portage/g-cpan-9999

The first two cases now work as expected (nice!):

• g-cpan -g OWL::Simple::Parser
• g-cpan -g OWL::Simple::OBOWriter

but the third one still fails:

• g-cpan -g OWL-Simple -> FAILS (due the package does not contain a OWL::Simple module)

Perhaps this last one should be treated in a different issue.

Good.
Indeed, this is enhancement about to support package names as well as module names.
I will create issue about this. And once it will be handled ;)
