Item12711: Fix up dependencies

Perl core and CPAN dependencies need to be listed as type "cpan"
or they are not correctly checked by configure.

Also a few dependencies are missing.

Item12711: Enhance the configure dependency check

If corelist is available (since perl 5.8.9), list the first available version of
perl for the core modules.

Also, we've switched InterWikis over to metacpan for information,
configure should be consistent.
