Jeff,
What I meant is the default Linux behavior is to first lookup
dependencies in the rpath, and then fallback to LD_LIBRARY_PATH
*unless* -Wl,--enable-new-dtags was used at link time.
In the case of Open MPI, -Wl,--enable-new-dtags is added to the MPI
wrappers,
but Open MPI is *not*
Thank you for the suggestion of 'configure ...
LDFLAGS="-Wl,--enable-new-dtags"'.
I'm still reading up on its meaning, but wouldn't that change the
behavior across all dependencies that are dynamically linked when I
build Open MPI?
I was specifically wanting *just* these UCX .so files to be

If Open MPI is built with this option, then LD_LIBRARY_PATH takes precedence
over rpath
(the default is the opposite
