 Existing configure fails with mpich-gcc. To begin with, it tries to
 install mpich-default, warning that it gonna fail. After removing mpi
 specification line, configure fails on:
 {{{
 -- Check for working Fortran compiler: /opt/local/bin/gfortran-mp-12 -
 skipped
 -- Found MPI_C: /usr/lib/libmpi.dylib (found version "2.0")
 -- Could NOT find MPI_Fortran (missing: MPI_Fortran_LIB_NAMES
 MPI_Fortran_F77_HEADER_DIR MPI_Fortran_MODULE_DIR MPI_Fortran_WORKS)
 -- Could NOT find MPI (missing: MPI_Fortran_FOUND) (found version "2.0")
 -- Found MPI_LIBRARY : FALSE
 CMake Error at CMakeLists.txt:74 (message):
   --> MPI Library NOT FOUND -- please set MPI_BASE_DIR accordingly --


 -- Configuring incomplete, errors occurred!
 }}}

 Yet `mpich` ''is'' installed with `gfortran`. The problem is that
 `${mpi.fc}` is not a name of a compiler, but only a prefix; naturally, it
 fails to be found.

 This works correctly:
 {{{
 pre-configure {
     configure.args-append \
         -DMPI_C_COMPILER=${mpi.cc}-mpich-gcc12 \
         -DMPI_Fortran_COMPILER=${mpi.fc}-mpich-gcc12 \
         -DMPIEXEC=${prefix}/bin/${mpi.exec} \
         -DLAPACK_LIBRARIES="-L${prefix}/lib ${linalglib}"
 }
 }}}

 Obviously, a general fix should be added either to the PG or the port. I
 just quoted what fixed the failure locally.

 Also, this should be added, otherwise `gcc-4.2` is picked and it fails on
 configure due to unsupported flags:
 {{{
 compiler.blacklist  *gcc-4.*
 }}}
