Thanks for the reply. Here is the chain of links:

ondra at august:~$ ll /usr/lib/libmpi.so
lrwxrwxrwx 1 root root 27 2008-02-09 01:56 /usr/lib/libmpi.so ->
/etc/alternatives/libmpi.so
ondra at august:~$ ll /etc/alternatives/libmpi.so
lrwxrwxrwx 1 root root 32 2008-02-09 01:56 /etc/alternatives/libmpi.so
-> /usr/lib/openmpi/lib/libmpi.so.0
ondra at august:~$ ll /usr/lib/openmpi/lib/libmpi.so.0
ls: cannot access /usr/lib/openmpi/lib/libmpi.so.0: No such file or directory
ondra at august:~$ wajig list-files libopenmpi1
[...]
/usr/lib/openmpi/lib/openmpi/mca_paffinity_linux.so
/usr/lib/openmpi/lib/openmpi/mca_topo_unity.so
/usr/lib/openmpi/lib/libmca_common_sm.so.0.0.0
/usr/lib/openmpi/lib/libopen-pal.so.0.0.0
/usr/lib/openmpi/lib/libmpi.so.0.0.0
/usr/lib/openmpi/lib/libmpi_f77.so.0.0.0
/usr/lib/openmpi/lib/libmpi_f90.so.0.0.0
[...]

So only the file:

ondra at august:~$ ls /usr/lib/openmpi/lib/libmpi.so.0.0.0
/usr/lib/openmpi/lib/libmpi.so.0.0.0

is installed. Any ideas why is it so? I think it could be some left
over, I know I had similar problems before. The solution was to
uninstall everything (I did try this), and then remove some links
using update-alternatives (I didn't try this yet).
