Bug 16756

Description of problem:
Boost was built with mpi in previous versions but not now.
See https://bugs.mageia.org/show_bug.cgi?id=11445

The openmpi BuildRequire is in fact still in the spec along with the "use mpi ;" which is added to the user-config.jam in a here doc.
All that is missing is the "mpi" in the %define boostlibs list.

However, it fails to create the boostlib-mpi library and there is a warning in the configuration:

warning: Graph library does not contain MPI-based parallel components.
note: to enable them, add "using mpi ;" to your user-config.jam
    - zlib                     : yes
    - iconv (libc)             : yes
    - icu                      : yes
    - compiler-supports-ssse3  : yes
    - compiler-supports-avx2   : yes
    - gcc visibility           : yes
    - long double support      : yes
warning: skipping optional Message Passing Interface (MPI) library.
note: to enable MPI support, add "using mpi ;" to user-config.jam.
note: to suppress this message, pass "--without-mpi" to bjam.
note: otherwise, you can safely ignore this message.

I have googled this and found one suggestion to add "using mpi:%{_bindir}/mpicc ;" to the user-config.jam, but this makes no difference.

I have also tried the boost-1.59 tarball with no change.

I am out of ideas, so assigning to maintainer :)

I will attach a diff of my current spec and a patch that I have made to allow it to build locally in iurt which it has never done without it.
