Just to add my own data point:

I am using my own build script in Ubuntu with OpenMPI, and I have performed many MPI-based runs (on my desktop and on clusters) with no hitch. While I'm not pushing for a switch to OpenMPI, an ubuntu-openmpi.cfg script would be convenient...

Comment (by eschnett):

 Is there a reason to switch to OpenMPI? If MPICH works fine, then let's
 stick with it for the release. Everything is open again one or two weeks
 from now.

 Regarding Boost: I don't think we need to add such a comment. If people
 want Boost, then they'll figure out that they either have to install it or
 to build it themselves (maybe via Cactus). Also, Boost 1.50 is quite
 outdated; Boost 1.58 is current, and with two releases per year this makes
 it four years old. I expect many packages to simply not work with Boost
 1.50.

 We are very shortly before a release. Now is not the time to clean up
 things. Now is the time to test things, and to fix important things that
 can't be worked around.
