Good call; thanks for the reminder. Thankfully, hwloc doesn't suffer from such issues (I just sanity checked the trunk and v1.0 to be sure).
IIRC, the main issues in OMPI surrounded the use of its wrapper compilers (i.e., trying to exec something with "gcc -m32" wouldn't work -- you have to split it into multiple tokens so that you only exec "gcc" and pass -m32 as the first argument).
