This is not failure to build; the error comes from the script, it can't find 
mpi.so.

I don't think this is a conflict between `python` and 
`python-for-extensions`. Rather, it is a conflict between 
libboost_serialization.so by itself (without rpath), and 
libboost_serialization.so built as a dependency of libboost_mpi.so (for 
which someone tries to set rpath.)

What does user-config.jam contain?

(Also... before spending too much time on this, consider trying 1.73 as 
well.)
