I've attached the patch that I've applied to PyQt5 snapshot. It relies on pkg-config, which, imho, is the right way to do it, but adds a build-time dependency to PyQt. The same effect could be achieved by hardcoding the LIBS variable to include -lpython2.7. As for sip, I've successfully built it after having configured it with a "LIBS+=-lpython2.7". Now the import works flawlessly, even from my embedded interpretor. Cheers, Johan Thelin
