That was the problem. I had updated Qt (but kept the old version on the machine) 
and also PyQt but PyQt was still using the old version of Qt. I only noticed 
this after removing the old Qt version when the configure.py was still trying to 
find the old Qt installation, despite correctly finding qmake from the newer one.

This is because the configure script builds a C++ program that queries Qt for 
the config info and I had the PyQt bin directory on my path, so it was finding 
the dlls in there from the old Qt version.
