Hi Jelle,
Actually, I think that fink is quite a good solution to run pythonocc. No
need to distribute Qt nor PyQt-x11, they're already provided and maintained
by the finkproject, with scintilla editor etc. I once built my own PyQt, for
MacPython, but this PyQt is linked to the qt4-x11 fink libs, and it was a
bit tweaky to get it compile. Since fink is required to run my PyQt, why
don't simply go with fink.
