[SciPy-user] Plea: Installing SciPy on Mac 10.4.9: _fftpack.so problems?

Hi Ariel,

Are you in fact using gcc 3.3? If so, note that gfortran must be used  
with gcc 4. As per the instructions on the page you referenced, first  
run 'sudo gcc_select 4.0' to start using gcc 4 before building scipy.

As for scipy not being available in python ("no module named scipy"),  
it stands to reason that since the build process terminated in an  
error, it would not be usable and hence not be installed.

Finally, if the above does not fix the problem, it would be helpful  
if in the future you could include the actual error lines in your  
message. These are the lines immediately before the  the "failed with  
exit status" lines that you copied to the bottom of the last email.  
These error lines can be distinguished as they should attempt to  
provide a (likely cryptic) error message somewhat more revealing than  

Best luck,
