Sorry, I should have said that I'd always deleted the build directories.
I now have a better idea about what the problem is.

python setup.py config_fc --fcompiler=gnu95 build_clib
--fcompiler=gnu95 build_ext --fcompiler=gnu95 install

works OK for svn versions < 6481 (where coremath was merged).
It fails for r 6481 and later.

However, simply,
python setup.py install
works OK for r 6481 and current (r 7039).

I'm using the old system gcc 4.0.1. Perhaps the problem is that my
gfortran (v4.3.2) is from MacPorts and was compiled to produce
intel-only binaries, rather than dual architecture binaries? But I'm
puzzled as to why specifying the fortran compiler should make any
difference -- I understood it isn't used to compile numpy.
