Thanks, Travis.

William, care to join in the numpy list with more details?  As you see, it is 
true that numpy is NOT supposed to require a fortran compiler, this is 
something that was very specifically discussed and agreed upon.  But we may 
need you to join in to get more information about how you are doing things, 
before more help can be provided.

Here's the list link for you to join in:
