[Python-Dev] Compiler for the Mac OS X version of Python 3.4

[Ned Deily]

Thank you all for your comments so far on this subject.  I have noted 
two separate issues raised here: one, how to build the Pythons provided 
by binary installers to get optimum performance (i.e. use more recent 
compilers); and, two, what OS X releases should we support with binary 
installers.  As I noted earlier, I've opened Issue19019 and I will 
update it with concrete proposals when we've complete the necessary 
testing and fixing of various build configurations, including of the 
sort Ronald and I outlined.  If you are interested in the details of 
this, please move that discussion to the bug tracker.

As to point two, I will put a stake in the ground here and declare that 
we will continue to support 10.6 with 3.4 batteries-included installers.  
For various reasons, 10.6 remains surprisingly popular (at a recent 
Python hackathon meetup in San Francisco, every person I helped who had 
a Mac was running 10.6) and it is not that old even by Apple standards.  
There are tradeoffs in how best to provide that support.  Among those 
tradeoffs are the impacts to those who provide binary packages for 
extension modules and third-party libraries, as Russell notes.  Again, 
after investigating and testing the nitty-gritty details, if it seems 
that a change in how we provide installers is warranted, we can discuss 
that on Issue19019 and report back here prior to any final decision.  
Also, at that time, it would be appropriate to consider a policy for 
long-term support of OS X releases; it's a bit premature to do so now.
