Thanks.

I managed to reproduce a good testsuite run by using the Build-Depends
from snapshot.debian.org from August 10th. I then gradually installed
newer packages from unstable until I found the culprit: It was the dbcsr
upgrade from 2.9.1 to 2.10.0 that broke it. That makes sense as dbcsr is
a close dependency of cp2k (and used to be part of its source tree).

I'll try to see whether there is something that can be done about this.
