Usually, Cactus use shared libraries, and they contain enough information to automatically find and use all necessary dependencies. Apparently you are using static libraries (see "libmpi.a" in the beginning of the error messages), and this requires listing dependencies manually.

This happens a lot.  It would be good to be able to put something into the optionlist which told the MPI thorn that it should use an auto-detected library, rather than building the library.
