I think that I actually may have this solved now.  It seems that I can resolve the issue by running "conda install gcc" then linking against the anaconda gfortran libraries rather than my system install.  The only problem is that installing gcc through anaconda causes anaconda's version of gcc to supersede the system version...

Anyway, not a numpy issue it seems, just an Anaconda packaging issue as you both said.
