Looks OK to me. Why would someone want to use BLAS without Fortran? |

…tran) Building OpenMPI without fortran is possible, and was already handled. Raising an install error we effectively renounce at clang+OpenMPI. build_environment : sets 'CC', 'CXX', and similar variables only if a compiler is found

Truncate dependency trees a bit more. These should really not end up in applications.

this is meant to prevent delayed compiler errors for packages which need MPI/Blas/Lapack with Fortran whereas specific implementations are build without Fortran.
At some point one would need to add an option
+fortranfor virtual packages (mpi, blas, lapack) and propagate it to particular implementations (openmpi,openblas,mpich, etc). Then ifs will change toif (self.compiler.f77 is None) and ('+fortran' in spec):. In other words, one would still need those ifs to throw an error.
