openmpi @1.6.4 +gcc45 non-standard names for executables

[dstrubbe (David Strubbe)]

The standard names for executables from OpenMPI are mpif90, mpif77, mpicc, mpirun, mpiexec. However, the ones provided by the openmpi port are all prefixed with "open", i.e. openmpif90 etc. I suggest this should be made clear somewhere in the port description, or alternately use the standard names (maybe the names were chosen to avoid conflict with mpich). I only discovered the actual names by reading through some tickets about this port. For example, the 'variants' output lists specifically the standard names, which are NOT the ones created by the port.

openmpi has the variants:
