Here is what I did:
in one terminal
$ ipcluster local -n 2
and keep it running. in another terminal:
$ git clone git://github.com/certik/sympy.git
$ cd sympy
$ git co -b par origin/par
$ python setup.py install --home=~/usr
$ python t.py

etc. There are some failures due to some tests in mpmath (the dps
needs to be fixed), but otherwise things more or less work.
Now let me try what you did too:
In [1]: from IPython.kernel import client
In [2]: mec = client.MultiEngineClient()
In [3]: mec.get_ids()
Out[3]: [0, 1]
so indeed, this seems like a bug in ipython on Mac.

I have CCed Brian, maybe he knows, as he developed most of that code.
