Tim,
a simple option is to
configure ... LDFLAGS="-Wl,--enable-new-dtags"
If Open MPI is built with this option, then LD_LIBRARY_PATH takes
precedence over rpath
(the default is the opposite as correctly pointed by Yossi in an earlier
message)
Cheers,
Gilles

Well, now it is a multi-line patch, and it is more hacky... but this
works for me. Suggestions for a better thing to do to upstream this
functionality would be appreciated.

Ugh, apparently my one-line patch to
openmpi-4.1.0/config/ompi_check_ucx.m4 wasn't sufficient on a fresh
install... debugging...

My environment modules were already setting LD_LIBRARY_PATH to point
to my UCX lib directory.
The real problem was that OMPI's config/ompi_check_ucx.m4 was
recording the full path to the UCX library if it wasn't found in a
standard system location (e.g. /lib, /lib64, /usr/lib, etc.).
That is
