This is by choice.  We now install all perl modules in a directory
that is versioned to match the Perl ABI version instead of the actual
version.  This makes the most sense since pkgsrc only allows a single
version of perl to be installed at a time.  If the Perl ABI is the
same between different versions of perl, then modules can be reused.

"site" modules are now also managed in the same way, using directories
that are matched to the Perl ABI version for the same reasons.

Yes.  This was a big change that I've posted to tech-pkg@ several
times already so that users would have a heads-up.  Using the new perl
framework, reinstalling modules won't be necessary after future perl
