FWIW, this sounds like a version mismatch or some kind. If you're getting "undefined symbol" errors, then it's quite possible/probable that you're somehow mixing multiple different versions of Open MPI. You might want to double and triple check all your PATH and LD_LIBRARY_PATH settings. "make uninstall" *should* work to get rid of an old OMPI install, but as Ralph says, it's definitely safer to rm -rf the tree containing the old Open MPI installation and/or install new versions of Open MPI in entirely new trees.
