No -- Running "apt-get dist-upgrade", or any of the graphical or
console alternates will give you _already compiled_ and _already
configured_ packages. That's a point of a distribution.

This whole discussion is about how to set up the default configuration
(with respect to IB warning which many folks do not have).

Also, step back for a second. Many higher-level MPI-using solution
'hide' all this plumbing. So someone advocation a Python-based or
R-based MPI solution will just tell people 'install the package'.
These user won't know the difference between Open MPI, LAM or MPICH
and wouldn't even know where to start.

That said, the task is indeed delicate at the Open MPI level as do of
course want genuine warnings for genuine failures. It is encouraging
how hard everybody tries to help 'the right way' about this.

Hth, Dirk
