[gentoo-devhelp] CPAN Modules

Hi!

I am writing an ebuild for ikiwki. That's a wiki compiler written in
Perl which uses a few modules from CPAN. At least it needs

Text::Markdown
URI
HTML::Parser
HTML::Template
HTML::Scrubber

Depending on some non global USE I would need a few more CPAN modules
I have to install. I would like to use g-cpan but there are a few
things which aren't nice to implement.

* I've asked myself if anybody already has made some kind of function
  set (eclass?) for automatically install CPAN modules.

* If I am installing g-cpan as dependency and the user has no overlay
  defined temporary ebuilds are created to install the Modules but
  they aren't tracked for update or removal if no longer
  needed. That's not very cute.

* The other possibility I see is to create an ebuild for each CPAN
  module I need. Does that conflict with the idea of g-cpan?

Thanks for any help in advance

I'd also be interested in the proper way to handle this. Have you
found a solution?

In particular, I am looking at the following modules from cpan:

Tk::DataTree
IPC::XPA

Thanks,
Henry

As fas as I can say it's the better way to create ebuilds for the CPAN
modules you need. The danger of using g-cpan is the fact that the
install is more or less a live install. But you can use g-cpan very
easily to create a default ebuild for the module you need. Put this
ebuild in your overlay and you have a versioned CPAN module on which
you can depend.
