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:
PkgSrc change:
  - Import package for perl module Data::Dumper::Names, which is a
    recommented requirement for Test::Most

DESCR:
This module is an alternative to Data::Dumper::Simple. Many people like the
aforementioned module but do not like the fact that it uses a source filter.
In order to pull off the trick with this module, we use PadWalker. This
introduces its own set of problems, not the least of which is that PadWalker
uses undocumented features of the Perl internals and has an annoying tendency
to break. Thus, if this module doesn't work on your machine you may have to
go back to Data::Dumper::Simple.
