I can't speak to ifort, but as one of the Open MPI maintainers for Debian, I
can assure you that the 1.2.* series works just fine on Ubuntu ... if you
rebuild from current Debian sources. 

I have forgotten what version of Open MPI made the 'freeze' for Ubuntu 7.10,
but it is probably something older if not even the 1.1.*.  I typically just
point my apt inputs to Debian unstable source (not binary packages) and then
fetch what I want to rebuild via 'apt-get source libopenmpi-dev'. That
requires some minimal Debian packaging skills you could learn from a number
of sources on the web,

Now, if and when you rebuild from source, I would make sure that you do not
have 'native' Ubuntu Open MPI and LAM '-dev' packages installed to avoid the
header / library mismatch you seem to be experiencing.

"small" Ubuntu updates?  When I roll my work machines to new Ubuntu releases,
it upgrades _hundreds_ of packages. Not what I call small.

Hope this helps, Dirk
