Install it:

$> python setup.py install
or link it:
$. python setupegg.py develop

I think pyston is clean and great, but I don't use it.  Here's my habit:

# cleanup occasionally, when there are major changes (such as updating your
OS or compiler), or when things are acting weird:
$> python setup.py clean
     # the following two are because setup.py clean cannot always be
$> find ./ -name *.so -exec rm {} \;
$> rm -rf build

# this is the only step I repeat on a regular basis:
$> git pull # update
$> python setup.py build_ext --inplace # build inplace

# do this only once:
$> python setupegg.py develop --user # I do --user, but you can install
wherever you want

And I have bash aliases to do all of the above things more efficiently.

I installed xquartz to get freetype; I imagine you could do `make -f
make.osx fetch deps` to get freetype, but I didn't.  I think the above
steps worked just fine after that (I would need a fresh 10.8 VM to be
perfectly sure).
