Comment(by vince@…):

 Okay, there are three files to build 2-way universal i386/x86_64 or
 ppc/ppc64 (NOT tested) numpy and scipy (that's the Portfile called
 Portfile_scipy, sorry for the wrong comment).

 To build universal numpy and scipy, you should first build a universal
 version of Atlas: I've posted a solution some time ago. Anyhow, you will
 need a multilib enabled version of gcc, preferably gcc44 or gcc45.

 The 'wrapper' file shall go in the files directory of both ports. It is a
 Bourne shell script that analyses the various calls to compilers,
 transforms the -arch flags into suitable -mXX and then calls lipo if
 necessary. In a way, it reproduces what the Apple gcc does. It might be
 buggy, but at least it works for numpy or scipy. The 'wrapper' is a
 template that gets transformed into a C, a C++ and a Fortran wrapper by
 the Portfiles. It also corrects missing flags when invoked to link dynamic
 libraries (a.k.a .so, here).

 Please test in a local repository if possible, and report any bug. It
 seems scipy.test fails test_iv_cephes_vs_amos_mass_test, but this seems to
 be a known bug (if I have figured out the few infos I found).
