PyQt's configure.py uses the information in your Qt installation's qmake mkspec files. So things should work if your Qt supports building with MinGW64. > 2. (Possibly more important).

I use the free Express version of MSVC2008. With the right magic this can be configured for 64 bits. I can send you instructions if you want to follow this route.
