Description of problem:
The 'devtoolset-6' and 'devtoolset-8' enable script exports a PYTHONPATH like this:

/opt/rh/devtoolset-6/root/usr/lib64/python2.7/site-packages:/opt/rh/devtoolset-6/root/usr/lib/python2.7/site-packages


Version-Release number of selected component (if applicable):
- DTS 8

How reproducible:


Steps to Reproduce:
1. run the DTS 8 enable script
2.
3.

Actual results:
PYTHONPATH becomes /opt/rh/devtoolset-6/root/usr/lib64/python2.7/site-packages:/opt/rh/devtoolset-6/root/usr/lib/python2.7/site-packages

Expected results:
- DTS doesn't have python
- The directories do not exist

Additional info:
this was originally introduced in the devtoolset-1.1 release.
