make openmpi compiler wrappers use currenly selected compiler

[mmoll@…]

It'd be nice if openmpi used gcc_select to select default compilers. Right now, the openmpi compiler wrappers (mpicc, mpicxx, mpif77) always use the C and C++ compilers in /usr/bin, even if /opt/local/bin comes first in the user's path. The changes to accomplish this are trivial:

• add a dependency on port:gcc_select
• patch the files in ${prefix}/share/openmpi to use /opt/local/bin/gcc instead of /usr/bin/gcc (similarly for C++ and Fortran).

This is highly necessary, because of this I having problems all the time with installed version of my openmpi.

One solution/workaround is to define the environment variables OMPI_CC, OMPI_CXX, etc. to the desired values (/opt/local/bin/gcc, /opt/local/bin/g++, etc.). This overrides the default settings. (This bug can be closed as far as I'm concerned if the maintainer is opposed to the original suggested enhancement.)
