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.

[PyQt] PyQt / SIP from an embedded Python interpreter
Hi, I've been experimenting with using PyQt and SIP from a Python interpreter embedded into a larger C++ application.
