>Description:
bsd.port.mk fixes PERL_VERSION based on what shipped with the particular
OS version, not based on what is currently installed and/or selected by
use.perl.  This causes many ports that depend on a newer version of perl
to refuse to build, despite the fact that a supported version of perl is
available.

>How-To-Repeat:
check out a current version of ports on an older version of FreeBSD (4.x for example).
try to build a port that requires perl 5.6 or later (e.g. net-mgmt/p5-Net-SNMP)

>Fix:
workaround is to edit bsd.port.mk and force PERL_VERSION to the version, though I suspect
there are some issues with this and I haven't fully tested it.  Between the system and port
instances of perl, and the myriad version libraries, perl module version management is a
nightmare on long-lived systems...
