Comment (by dstrubbe@…):

 This seems to be a MacOS-specific issue. I found a thread and ticket about
 it at http://www.open-mpi.org/community/lists/users/2011/11/17862.php and
 http://www.open-mpi.org/community/lists/users/2013/01/21077.php. The fix
 mentioned in the first (-Wl,-commons,use_dylibs) is present in the version
 of OpenMPI we are using, and is correctly added by the configure script on
 my machine. I tried manually adding the second fix ( -Wl,-flat_namespace)
 to my link-line with openmpif90 and it doesn't seem to make any difference
 unfortunately.
