On recent 5-CURRENT, there is no Perl wrapper. It is therefore possible

that /usr/bin/perl5 doesn't exist, which violates some of use.perl's
assumptions.  Take care of this case. [1]

Also in the case of a recent 5-CURRENT, automatically perform
"use.perl port" during package/port installation.  This helps the
installation of sysinstall's new "Perl distribution", in that
sysinstall doesn't need to do this explicitly as Yet Another Special
Case. [2]

PORTREVISION bump after all this good stuff.
