I'm trolling through the disaster that is my inbox and finding some orphaned email threads -- sorry for the delay, folks!

We have some developers in the OMPI community who are passionate about adding only the bare minimum set of compiler / linker flags that are necessary for correctness. Rpath has come up again and again (i.e., add rpath into the set of flags that is added by the wrappers) and has been soundly rejected because it is not part of that "bare minimum set."

That being said, I think the objections would be *much* less if adding rpath was optional (and probably not the default) -- e.g., perhaps rpath is added to wrapper compiler flags if OMPI was configured with a specific command line flag, or a specific MCA parameter is enabled.

We'd be very happy to accept patches for this kind of thing...
