If Apple drops support for gcc in 10.9 I guess we have to go this route, 
but please be careful. Every time you add a new version of python for 
MacOS X it means that folks providing binary installers (e.g. for numpy) 
have to provide another binary, and folks using those installers have 
another chance of picking the wrong one.

If you do make a 10.6-only installer, what is the minimum version of 
MacOS X the modern compiler would support? 10.7 gives a more measured 
upgrade path, but 10.8 gives a better compiler.
