This is not true anymore. Packager::Utils will do that for (some)one.

See RE: 1
Also: Packager::Utils doesn't add that line when it knows it's removed
from core (marked as depreciated even in next devel-version).

No, Packager::Utils inspects META uploaded to CPAN. Packager

No, in that case always the separate package is referred.

Currently pkgsrc comes with one perl only. If we do multiple perls as
we do for python, we (I, patches welcome) have to modify Packager::Utils
to fall back to ›DEPENDS += {perl>=5.10.1,p5-CPAN>=1.9301}:../../devel/p5-CPAN‹

Currently P::U cares only for the version contained in pkgsrc (or better:
packaged version - theoretically any packaging system can be plugged in)
or later in case of deprecation.

I recently talked to the MetaCPAN folks to enhance metacpan to allow updating
packages by knowing the distribution only (refer DESCRIPTION etc. from
primary module of distribution - what is somewhat difficult for eg. 
IO-Compress).
