I know that the way how the compilation of PyQGIS works now isn't
optimal at all, however I wasn't able to figure out any better
solution. Python modules sipconfig and pyqtconfig do all the hard work
detecting correct parameters for compilation for all supported
Looking at sipconfig I see it supports universal builds - try this:
in configure.py.in add argument universal='/Developer/SDKs/MacOSX10.4u.sdk'
to sipconfig.ModuleMakefile() constructor - when creating variables
makefile_core and makefile_gui
It should do exactly the same as Tom has written manually to makefiles...
