[SciPy-user] SciPy Install failure: dfftpack not found

Help, Please! SciPy installation is giving me fits. After a recent HD  
crash, I'm trying to reinstall my Python system.

Installing using he bash command in OS X 10.4.5

     Foo:~/Desktop/scipy-0.4.6 bar$ sudo python setup.py bdist_egg

proceeds just fine until it tries to compile the fftpack. The  
dfftpack can't be found, even tho the directory  ./Lib/fftpack/ 
dfftpack exists and contains the Fortran source files. See ERROR  
below. The same error occurs for

     Foo:~/Desktop/scipy-0.4.6 bar$ sudo python setup.py install

I've read and followed, I believe, the instructions from the  
Installation web page. The info for my Python system as it stands is  
given below. If there's any more diagnostic info needed, I'll be  
happy to pass it along.

I'd appreciate any help in solving this problem.
