I've seen this myself and cannot work out what the problem is.  Assuming you don't need to use the QtNfc module the easiest thing to do is to disable it before running configure.py. One way to disable it is to rename the QtNfc directory containing the .h files in your Qt installation to something like QtNfc-disabled.

I will add a flag to configure.py to specifically disable a module.
