make check fails when the 1.8.1 is built with an external libltdl. The system libtool did not have those headers so we provided an external installation of libtool. The source compiles and builds but fails this test:
make: *** No rule to make target `../../opal/libltdl/libltdlc.la', needed by `dlopen_test'. Stop.
When building with --disable-dlopen which disables libltdl anyway or the internal make check returns no errors. Just curious for an explanation... if there is any.
