No, you miss the point.  You can't do that in the global context in the Portfile. It doesn't matter what it returns on my system, you can't do it there because it needs to work even if  /opt/local/lib/libboost_mpi_python-mt.dylib isn't present (such as when you want to install it fresh, or you are generating the PortIndex, ...

Right.  It doesn't work unless someone actually has that file in place.

Yep.  Some won't.  You can put in a verification to check that, but it needs to be done during an appropriate build phase, not in the global context.
