When building from source on mac os x 10.4 ppc
either from the tarball 0.5.2 or svn, I get the following error,

after installing gfortran and fftw as per the scipy web instructions

svn co http://svn.scipy.org/svn/scipy/trunk scipysvn
cd scipysvn
export MACOSX_DEPLOYMENT_TARGET=10.4
sudo python setup.py build_src build_clib --fcompiler=gnu95 build_ext  
--fcompiler=gnu95 build

snip.....

/usr/bin/ld: flag: -undefined dynamic_lookup can't be used with  
MACOSX_DEPLOYMENT_TARGET environment variable set to: 10.1
collect2: ld returned 1 exit status

-lgfortran -o build/lib.macosx-10.4-ppc-2.5/scipy/fftpack/ 
_fftpack.so" failed with exit status 1

Looking in the archives on scipy.org I found a couple of other people  
who had this problem in June but there was
not mentioned a fix.

anyone have a fix for this?
