You are indeed correct.  The stdlib uuid.py loads libuuid via 
ctypes.util.find_library, which (with our patchset) finds the actual DLL 
name via the import library.  (This is also true on ELF platforms, 
although the actual mechanism is somewhat different.)

I have added libuuid-devel to both python and python3 requires.

Only by luck; it's actually necessary for both arches.

Thanks for reporting,

Yaakov
