You don't want to have a variable named like that ;)

It looks like you need extensive patches for this, especially to the
pkg_install in the base system, so this solution won't happen soon and
is not backwards compatible to older systems.
Apache and perl ports normally conflicts, so there can be only one, and
you can solve it by requiring the port you want to live with. The point
is that defaults should not change, depending on other options that can
change during the build. Defaulting to different perl versions depending
on OSREL is ok, since this doesn't change. Defaulting to different python
versions depending on USE_ZOPE is problematic.
