Subject: Re: [OMPI users] Setting RPATH for Open MPI libraries
From: Jed Brown (jed_at_[hidden])

Jeff, we are averaging a half dozen support threads per week on PETSc
lists/email caused by lack of RPATH in Open MPI for non-standard install
locations. Can you either make the necessary environment modification more
visible for novice users or implement the RPATH option?
