You can also try setupegg.py develop, which will setup some symbolic
links to make the globally installed sympy always point to the git
version.  Then, whatever branch you checkout with git will
automatically become the globally installed version.

Regarding your other way (and actually this way too), make sure that
the command "python2.7" points to the macports Python (run "which
python2.7").  If you just use ./setup.py instead of python setup.py,
it will use the default Python (the first in your path).  You can also
try /full/path/to/macports/python2.7 setup.py (probably
/opt/bin/python2.7).
