Yes, I saw that now:
I used homebrew python without thinking.
And sure, whenever I build Python myself, I do use the 10.6 setting.

Now I understood that this setting defines the minimum for extension
modules, and PySide still is one. Forgot that completely, because
it compiles so long.

After looking into the Cellar, everything was clear: :-)

/usr/local/Cellar/python3/3.4.0_1/Frameworks/Python.framework/Versions/3.4/lib/python3.4/_sysconfigdata.py:
'MACOSX_DEPLOYMENT_TARGET': '10.9',

This setting is inserted unconditionally from the OS version in the
python formula. Yay!

So, the versions that I built are fine, just a bit over-done.

Well, these versions also minimize possible incompatibilities ;-)

Thank you for solving the knot in my head.

Btw., I was not aware that the wheels may be just renamed. I assumed
that some more knowledge is sitting inside to verify the right version.
Sadly, things are way more primitive that I hoped for.

cheers & thanks -- Chris
