Description of problem:
blacs requires explicitely lapack on runtime. It's completely fine to build against it, but on runtime, when the atlas libraries are installed and lapack isn't, blacs seems to work fine too.
Version-Release number of selected component (if applicable):
No specific requirement of lapack, so any "liblapack.so.3" is picked up automatically.
Building a MPI-parallel version of cp2k seems to work fine without the explicit requires.

Seems sane. I'll take care of it. Thanks for the report.
Hmm, looking at it deeper, I don't think blacs is actually picking up a "liblapack.so.3" dependency automatically. It doesn't seem to need to build against it either. :/
I'm just going to make an update that drops both the BuildRequires and the Requires. Please test and confirm that it still works correctly.
Got the builds from:
But for cp2k there is blas needed, I have no lapack installed.
Basic testing works fine, cp2k builds.
Looks good to me. Thanks.
