Hi Thomas
You're a lifesaver. It helps to get expert advice! It didn't work initially,
since I also had to add that extra path for the Visualisation section in
setup.py, but I knew what to look for with otool.
Some the samples are working now, I didn't enable GEOM/SMESH so rebuilding
those now as well.
Thanks!
Benjamin
