Uh, I'm not sure what you're trying to do here? REQUIRES_EXCLUDE_FROM 
lists files *in your package* which shouldn't be considered for 
automatic dependency detection. I shall tweak the documentation to make 
this clearer.

Excluding /usr/lib/python3.NN/site-packages when there are no files 
there isn't going to do anything.

This seems to work:

> REQUIRES="python3 python3-requests"
> REQUIRES_EXCLUDE_FROM="usr/bin/units_cur"

(It's probably a bug in cygport that it can't handle this (rare) case 
particularly well, but I'm not sure what to do about it...)
