Pete,

  We actually just ran into the same question.  So I'd like to hear
anyones answer as well.  For now what we did is before the call to
setup() we modify our list of Extensions.  If we are on linux we do it
one way, on windows another.  Not pretty but it works.  We have a little
easier situation then you though because our "other library" is a python
.so so we just import it to find the path....
