not surprisingly, this produces the same error message(s) as those from
testase.

I have followed all that, and I have also re-installed ASE.
However, the outcome of that is not completely encouraging:
Instead of only one test (hcp) failing, I now get two fails: hcp (again,
with the same sympton) and now also oi:

My suspicion is that "yast --remove python-numpy" may have deleted also
other dependencies.
Also, I am a bit worried about the curious mix of .../lib/... and
.../lib64/... in the above snippets, but maybe this only reflects my
lack of knowledge about python setups.

Any ideas are welcome!
