Initially I just installed the python3 RPMs and when I tried running 
manually it was still error'ing on configure due to finding python2.

Even after adding EXPORT PYTHON=python3 to my ~/.bash_profile I was 
seeing the same.

By adding PYTHON => 'python3' to build-farm.conf I saw that the error 
changed to indicate missing python3-devel package. Once I installed 
that, everything went green.
