Thanks for the explanation about needing a fortran compiler. macports states that it is building gcc44, and after several hours, I don't see any real progress . I have two 'f951' tasks running, each consuming 2.8GB of real memory (and as much as 32GB of virtual).
I've got 12GB of RAM, but my 2 x 8Ghz Dual-core Xeon Mac Pro is almost unusable while this build is running. The instructions for building scipy for Mac OS 10.7 refer to installing gfortran from http://r.research.att.com/gfortran-lion-5666-3.pkg . Is there any way to build scipy in macports using that compiler? It looks like the scipy dependencies assumes that macports needs to build a fortran compiler from source.
