cst.signal.build() could not generate correct rspectra.so for EPD(32-bit) python

[qliu19]

Today I happened to regenerate rspectra.so under cst folder and found it didn't work properly as it used to. I am using a 32-bit python (Enthought) on mac os x 10.6.8.
I suspect it could be due to an update of numpy (currently it is on 1.7.1) since I was able to compile rspectra correctly before.
Finally I ended up build it with f2py using the following snippet (following the method in http://cens.ioc.ee/pipermail/f2py-users/2009-August/001873.html):

export LDFLAGS='-m32 -Wall -undefined dynamic_lookup -bundle'
 f2py -c -m rspectra --f90flags=-m32 --f77flags=-m32 rspectra.f90
