[mvapich-discuss] Missing make dependencies in 1.8 latest

[Jonathan Perkins]

Craig:
Parallel builds do not work with versions of MPICH2 prior to 1.5a.  Our
latest release of MVAPICH2 is currently based on MPICH2-1.4.1p1 so we
inherited this limitation as well.

Future version of MVAPICH2 will be based on MPICH2-1.5 so this problem
will no longer exist at this point.

For more information on the parallel build issue please see
