[ExM Users] Swift/T using wrong Python

[Tim Armstrong]

Hmm, so it's probably picking up the system Python by default.   This may
be an oversight on our part - I'm creating a bug to look into it.  Our
build should be linking it to your other python library but isn't.

As a workaround, you can override this with the DYLD_LIBRARY_PATH
environment variable on Mac OS X.

If you add the directory with your preferred python .dylib file to that
environment variable, it should link against that version of python instead
of the system one.

E.g.

export DYLD_LIBRARY_PATH=/path/to/anaconda/lib

I *think* this should give you a way to work around it in the meantime.
