I don't understand.  Isn't /usr/lib/libmpi_f77.so.0 listed in your dpkg
-L output above?

Ah, I think I see the problem.  /usr/lib/libmpi_f77.so.0 is symlinked to
libmpif77.so -- which is an alternatives symlink created by the -dev
package postinst.  This is broken, it needs to link to a real shared
library with that soname.  The shared lib package can't depend on
symlinks in the -dev package.

Okay, but the busted links between libopenmpi1.3 files clearly make this
a bug in libopenmpi1.3, not Elmer, right?
