Comment (by Roland Haas):

I played around with OpenSuSE a bit over the break. Turns out that it sets CONFIG_SITE and that causes problems in the release branch of the Einstein Toolkit (will be fixed in development soon).

For now the workaround is to add:

unset CONFIG_SITE

before you compile. See the OpenSuSE section of the prerequisites section of https://github.com/einsteintoolkit/jupyter-et/blob/master/tutorial-server/notebooks/CactusTutorial.ipynb
