13560	Cannot build --with-python --with-mpi --python-buildid=py36 python=3.6	Dimitri John Ledkov <xnox@…>	Matthias Troyer	"For a long time, debian would do multiple build configs of boost.
First, build boost without python.
Then build boost for each supported python version, including mpi/mpi-python/numpy.

However, this does not appear to quite work. Previously boost_python introduced boost_python2 and boost_python3 libraries pointing at the default versions of respective major series. But in master/1.66/1.67 these appear to be gone.

However, mpi Jamfile still refers to boost_python3 library which no longer exists.

Either it is a bug in boost_python that it has dropped boost_python2 and boost_python3 aliases.
Or it is a bug in mpi Jamfiles and it should stop using boost_python2 and boost_python3 aliases and simply compile against ""boost_python"" and use a matching buildid.

I've proposed a patch to make mpi build against 'boost_python' without iterating for 2 3 major versions here
