I'm not sure I understand.  libtool exports this environment variable
before invoking the linker.  If your linker is mpicxx, and that invokes
g++, then LD_RUN_PATH should be available to g++ unless mpicxx
explicitly unsets the variable, no?

This looks like an OpenMPI issue to me, if any.  But maybe you should
explain in more detail, and with an example, what goes wrong for you.

Hope that helps.

Cheers,
