I was trying out easybuilders/easybuild-easyconfigs#2621 and I ran into an issue with HMNS. Deep in it's list of dependencies there is a build dependency on xcb-proto, which inside has a system dependency for Python. For a hierarchical naming scheme the robot is the default and the naming scheme requires the easyconfig to be parsed, so the easyconfig of xcb-proto will always get parsed, even though it is not part of the build process for Python. EBROOTPYTHON was being set as the file was parsed, which was causing the build to stop hard because it thought the module was loaded.

EasyBuild framework unit test suite PASSed (see https://jenkins1.ugent.be/job/easybuild-framework-pr-builder/2828/console for more details).

This pull request is now ready for review/testing.

Please try and find someone who can tackle this; contact @boegel if you're not sure what to do.

@ocaisa: can you retry that on top of this PR? It should fix the problem.

Fix works, thanks @boegel !

Great, thanks for the confirmation @ocaisa, going in!
