Uhm, never thought about it... So, you say my unreflected blind trust in the
authors of ./configure scripts and Makefiles might be unjustified? ;-)

O.k. I chown-ed all the sources and compile them now as normal user.

Is there any risk in replacing the current MPI-enabled HDF5 library with the
hdf5-serial-dev? Will the software that I compiled with this one still work?
I can give it a try anyway.

The -DMPICH_SKIP_MPICXX and -DOMPI_SKIP_MPICXX parameters you proposed in
the other thread also did the job, and I could compile.

Thanks a lot! I really made some progress!
