g-cpan -i <module_name> does not add the package atom to the world file. This means that emerge --depclean will always want to remove any g-cpan installed modules and their dependencies.

*** Bug 144207 has been marked as a duplicate of this bug. ***
@mcummings: Either we get rid of the --oneshot option (g-cpan l. 401) or we create a method in Gentoo::Portage to record packages in the world file. Easiest way would be removing the oneshot option. What made you add this option? I cannot think of any reason right now why it's in there.
The 'original' version of g-cpan emerged everything in the overlay one at a time (regardless of what was passed, which meant everything in your g-cpan overlay was put in world). This was fixed in the new version (relying instead on the passed list) but the --oneshot wasn't removed.
Fixed in svn.
