Confusingly, or interestingly, as root 'python -c "from scipy.optimize
import minpack2" ' produces exactly nothing. With my own userid I get
what I had before, i.e.:

This prompted me to check $PYTHONPATH, which is simply empty for root
but contains various stuff for my own userid --- one entry comes from
the ADF package, others from me, in probably failed attempts to add in
what PYTHONPATH "should" contain besides what ADF wants (which points to
some ADF-internal python things). Hence, when I delete PYTHONPATH
completely in my userid, the command
   python -c "from scipy.optimize import minpack2"
also produces no response, probably indicating that it just works fine.

In fact, this eliminates the error I got for the hpc test.
However, now I am stuck with the (new) error in the oi test:

which I did not have after my first ASE installation attempt...
