The attached patch is what I came up so far and it looks quite promising
to me. But I'd really like to have it reviewed before I apply it to
trunk.

It splits the libs to both packages. libopen-pal and libopen-rte are
required by mpi{run,exec}, so I put them into libopenmpi1. I did so as
well with libmca_common_sm and the private .so files though I'm not sure
if they're needed by these tools. Dirk, do you know by hard? I have to
look that up otherwise. (I think they're dlopen'ed, aren't they?)

All other libs went into libopenmpi-dev. Those conflicting with other
packages are handled by u-a. Links to .so files are just created in the
libopenmpi-dev package, libopenmpi1 creates links to .so.0 files. I have
in mind this is correct but it's really late here and that makes me
doubt that these changes make sense. Anyway, I think it's at least a
step further to the solution, if not the solution itself.

As a last note, I successfully build with the patch. I did not check the
packages, not even with lintian. There's a change they won't work at
all. I'll leave that for tomorrow.

Best regards
Manuel
