I install OpenMPI in directory A, then later move it to directory B and compile my own code with mpicc or mpic++. Of course I need to set the OPAL_PREFIX environment variable to point to directory B. This works fine on all my platforms (RedHat, Ubuntu, Fedora, Debian, etc) but still fails on Mac OS X 10.7 and 10.8 with the following error:

Besides setting the OPAL_PREFIX, also the DYLD_LIBRARY_PATH needs to be adjusted to point to the new /Users/eheien/B/lib location.
