Log message:
Bump the PKGREVISION for all packages which depend directly on perl,
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.

The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.

sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!

Log message:
Add devel/p5-Internals version 1.1.  This is needed by
p5-PerlIO-via-dynamic when using perl-5.10.

This module allows you to write-protect and write-enable
your Perl variables, objects and data structures.

Moreover, the reference count of any Perl variable can
be read and set.
