I have been tinkering with a custom web-app ebuild that uses quite a few perl modules not in portage.
I am curious if it would make sense to have the ebuild run g-cpan to build the dependencies rather than maintain a overlay.
Are there or have there ever been ebuilds that do this?
I am looking for an example.
Seems like it might make maintaining perl easier.
Thanks in advance.

Ebuilds can't call g-cpan, or any other tool that calls back into portage (emerge, ebuild, repoman, equery, ...).

OK Thanks.
It would be cool if portage could somehow call g-cpan.
Say I need Rose-DB-Object I could make my ebuild depend on
virtual/perl-Rose-DB-Object
Portage could see that Rose-DB-Object is not in the tree and it will build it with g-cpan
making a perl-gcpan/Rose-DB-Object and a virtual/perl-Rose-DB-Object.

Or perhaps if a ebuild depends on anything perl-gcpan/* call g-cpan to install those deps.
