Hi John, I don’t think an external dependency is going to fix this.
In your build area, do you see any .lo files in opal/util/keyval ? Which compiler are you using? Also, are you building from the tarballs at https://www.open-mpi.org/software/ompi/v4.1/ ?

I also tried ./configure --prefix=/usr/local/openmpi --disable-silent-rules --enable-builtin-atomics --with-hwloc=/usr --with-libevent=external --with-pmix=external --with-valgrind (similar to what is in the Fedora spec file for OpenMPI) but that produces the same errors. Is there a third-party library I need to install or an additional configure option I can set that will fix these? John
