For that you want:

pip install ipython[notebook]

Tornado is the current fly-in-the-wheel-ointment, because it does
invoke a compiler, and I think the current version crashes on OSX
without a compiler.  There's a bugfix in master, but maybe they will
agree to put up a binary wheel on the next release.

I think soon just Python.org python will cover it, with binary wheels
going into the virtualenvs.

I had a quick look :

$ delocate-listdeps Pillow-2.4.0-cp27-none-macosx_10_6_intel.whl -a -d
/Library/Frameworks/Tcl.framework/Versions/8.5/Tcl:
    PIL/_imagingtk.so
/Library/Frameworks/Tk.framework/Versions/8.5/Tk:
    PIL/_imagingtk.so
/usr/X11/lib/libfreetype.6.dylib:
    PIL/_imagingft.so
/usr/lib/libSystem.B.dylib:
    PIL/_imagingft.so
    PIL/_imagingmath.so
    PIL/_imagingtk.so
    PIL/_imaging.so
/usr/lib/libz.1.dylib:
    PIL/_imaging.so

I don't know if libz is safe to depend on, I guess it is.

I think libfreetype comes from XQuartz on later OSX, I can't remember
where the Tk.framework came from.  In any case, delocate-wheel copies
those guys and puts them in the archive, wheels here;

https://nipy.bic.berkeley.edu/scipy_installers/

pip install -U pip
pip install -f https://nipy.bic.berkeley.edu/scipy_installers Pillow

Do they work for you?

Cheers,

Matthew
