Yes very sure since I did not have a python from python.org when I tried
first time. Explicitly starting python through
/System/Library/FrameWorks/Python.framework/Versions/2.7/bin/python and
fetching sys.path still shows no site-packages under the /System/
hierarchy, but the one from /Library.

I've meanwhile installed pip using the System python and that was placed in
/Library as well.

However I do notice now that my /usr/bin/python is slightly larger than the
python2.7 binary. No idea wether thats normal or not (a hunch tells me this
is because that one reads out some OSX config to determine which Python I
want as default), but at least the dates of the two are matching (Sep 10th
2014)

All this is on a fresh OSX 10.10.
