Arch Linux has recently switched its 'python' package to the Python v3 branch. SIP and PyQt still require the 'python2' package, probably because the unpatched D-Bus Python bindings currently won't work with Python v3.
I'm guessing that some other Linux distributions will continue using Python v2 for a while yet. Due to this uncertainty, I'm thinking that the Makefiles of my applications should detect whether PyQt is attached to Python v2 or v3. Doing so will save me from having to hard-code something like "#!/usr/bin/env python2" into the main executable file, only to be disappointed after finding out that some Linux distributions have already built PyQt on Python v3. I realise that I could just search for the "/site-packages/PyQt4/" directory, but I want a much cleaner solution that won't slow down the installation processes. So, how should my Makefiles determine this necessary information?
