if a port needs 2.x then set MODPY_VERSION=${MODPY_DEFAULT_VERSION_2}.
This commit doesn't change any versions currently used; it may be that
some ports have MODPY_DEFAULT_VERSION_2 but don't require it, those
should be cleaned up in the course of updating ports where possible.
Python module ports providing py3-* packages should still use
FLAVOR=python3 so that we don't have a mixture of dependencies some
using ${MODPY_FLAVOR} and others not.
since SHARED_ONLY support was removed across the ports tree the perl module
no longer adds it, so it must be done manually for any perl ports that
provide perl shared-library modules (i.e. libdata/perl5/site_perl/$ARCH/*.so)
and you must not remove them from WANTLIB even if they show as "Extra".
configure checks for php version using $PHP_VERSION '>' 5.0.0, which wont
fly with our sh... and since we dont have php4 anyway, assume PHP_SWIG will
be php5. Was probably broken before that..
for consistency with the gem/extconf ports.
Update non-gem/extconf ports that relied on the previous
default of ruby 1.8 to explicitly specify it.
