Stefan, thanks a lot for investigating it.

I still wonder why it worked with 3.4. Maybe, it was because the python
binaries were not in the same directory with stdlibs.

Hmm, I am a bit scared to do such change at this stage. I am not sure if
the stdlibs are 100% backward compatible, it there are not disabled some
features on some crazy systems. Note that we already have 3.5.0-rc3
which is supposed to be final.

One possibility would be to try system stdlibs in daily builds. Ask
people for testing. If we do not get any complains, we could try this
with 3.5.1`bug fix release that should get release 4 weeks from now.

People could remove the libs in 3.5.0 as a workaround.

How does that sound? Maybe, we should discuss this on TSC.
