Thanks for the promp feedback :-)
That was easily fixable by installing a version of clang in macports :-)

In order for it to compile with MacPorts, you'll have to
1) install MacPorts
2) fix the PATH to start with the MacPorts paths
3) port install openmpi-devel-clang40
4a) port select --summary
fix these :
Name        Selected                       Options
====        ========                       =======
clang       mp-clang-4.0                   mp-clang-4.0 none
gcc         mp-gcc6                        mp-gcc6 none
llvm        mp-llvm-4.0                    mp-llvm-4.0 none
mpi         openmpi-devel-clang40-fortran  openmpi-devel-clang40-fortran
openmpi-devel-gcc6-fortran openmpi-mp-fortran none
4b) port select --set <name> <option>
5) port install openssl

./configure LDFLAGS=-L/macports/lib    CFLAGS="-O2 -I/macports/include"

I've uploaded two files :

that might be of help to others :-)
they _do_ reflect my custom install, so you might have to fix the paths
to your preferences ;-)

so now I've got it to compile successfully without mpi support ! :-)
