the joke on sysadmin/programes (im one of them) is that we give a correct 
answer
to the wrong qwestion :-)

the problem is not compiling modules(*), that works fine, it's the install.
there is a bug somewhere, where the check if installed is WRONG, so
it deinstalls the LAST installed module, but installes the correct version!

my workaround was to tar lib/python2.7/site-packages, install the 3.2 modules
(which deinstalls the 2.7) and when done, untar the 2.7.

the virtualenv is a nogo here, we have several hundred users!

the bsd.python.mk needs urgent cleanup, it's most confusing

cheers,
	danny

*: make PYTHON_VERSION=3.2 clean {de,re}install

PS: keep me in the CC, I'm not subscrided to ports.
