The link from /etc/alternative/libmpi.so point to a .0 we do not have.
So Manuel, could it be that the third line here
update-alternatives \
--install /usr/include/mpi mpi /usr/lib/openmpi/include 5 \
--slave /usr/lib/libmpi.so libmpi.so /usr/lib/openmpi/lib/libmpi.so.0 \
needs a fix to
--slave /usr/lib/libmpi.so libmpi.so /usr/lib/openmpi/lib/libmpi.so \
?
Thanks for your patience, Ondrej. I think we're all on the same page now.

|
| $ touch base.tgz
| $ sudo pbuilder --create --basetgz ./base.tgz --mirror
| http://ftp.cz.debian.org/debian
| $ sudo pbuilder --login --basetgz ./base.tgz
| # apt-get install libopenmpi-dev

| # ls -l /usr/lib/openmpi/lib/libmpi.so.0
| ls: cannot access /usr/lib/openmpi/lib/libmpi.so.0: No such file or directory
|
|
| (I think you can substitute ftp.cz.debian.org for ftp.de.debian.org,
