Chris,

I just uploaded a quick log of what I did to accomplish exactly this to

   https://gist.github.com/2015652

I do have the problem that within the virtualenv, something with the
console's not working right, as iPythons help doesn't work properly, and
I cannot launch applications which open windows (except for ``ipython
pylab=wx``) ...

I hope it still helps ...

Cheers,
Andreas.
