You can try this in /etc/make.conf:
# Global setting
PYTHON_DEFAULT_VERISON=python2.5
# some/py-port requires python2.4 (install py24-... port)
.if ${.CURDIR:M*/some/py-port}
PYTHON_DEFAULT_VERSION=python2.4
.endif
It's not perfect, because some pyNN-... ports still share some
files, esp. scripts in /usr/local/bin, etc., but it works for many
Python ports already. ;)
