FWIW - they "python(abi) = ##" requires is added by /usr/lib/rpm/pythondeps.sh 
as part of the standard rpm dependency generation.  So yes, for this to work 
with the scl, either the scl needs to provide "python(abi) = 2.7" or you will 
need to disable the automatic requires generation or filter out the 
python(abi) line.

We're all new to this SCL stuff.... :)
