[SciPy-user] SciPy svn build chokes on swig

[Chris]

Building SciPy from SVN on OS X 10.4, which has worked up until today,
chokes when it tries to look for swig:

swig: scipy/io/nifti/nifticlib.i
swig -python -Iscipy/io/nifti -Iscipy/io/nifti/nifticlib/fsliolib 
-Iscipy/io/nifti/nifticlib/niftilib -Iscipy/io/nifti/nifticlib/znzlib -o
build/src.macosx-10.3-fat-2.5/scipy/io/nifti/nifticlib_wrap.c -outdir
build/src.macosx-10.3-fat-2.5/scipy/io/nifti scipy/io/nifti/nifticlib.i
unable to execute swig: No such file or directory
error: command 'swig' failed with exit status 1

I was building just after a successful build and install of numpy
from SVN minutes prior.
