Josh,
   Pymol upstream changed their build procedure in 1.5 so that they no longer 
support...

python setup.py build
python setup.py install

but only...

python setup.py install

which both compiles and installs pymol. So I guess I may need to have an explicit
install phase instead of using the default python port one in order to pass CC
and CXX in front of the 'python2.x setup.py install' if build.env isn't available
in the install phase.
