There's some extra special mojo that needs to be supplied when cross-compiling Open MPI (e.g., a file that specifies all the ./configure answers for tests that it can't run in a cross-compiling environment).
The wiki page Ralph was talking about was referring to instructions on how to create this answer file. I can't seem to find it, either. Brian -- any idea what happened to that wiki page? I've pinged our ARM contact to see how he compiles OMPI for the ARM platform.
