Ok, thank you!
The compile seems ok now. However, I have segfaults during run (see
listing). I had those also on my computer at work, but could fix this by a
provided replacement for the source file responsible for
MPI-communication... That doesn't work here. Anyway, is the error listing
below suspiceous for MPI-communication problems?
