 Priority:  Normal              |   Milestone:  Port Enhancements
Component:  ports               |     Version:  1.7.0            
 Keywords:  openmpi gcc_select  |        Port:  openmpi          
--------------------------------+-------------------------------------------
 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).
