py2app and eggs

[franko353]

This may be common information, but I had trouble finding it.

I was getting an ImportError whenever I tried to run a built app from
py2app.

It turns out that using py2app version "0.3.6", it was having trouble
with zipped egg installs.

I had to move my zipped egg file to a temporary location (from
sitepackages) and issue a ``easy_install -Z somepackage.egg``.

Once I did this, I stopped getting the ImportError and everything
worked.
