When we specify --with-devel-headers, we also emit a copy of libpmix. However, that library was built against the OPAL libevent component, which means all the libevent functions are prefixed with OPAL names. So ensure that the emitted libpmix is linked back against libopen-pal so those symbols will be resolved.
