[SciPy-user] scipy 0.5.2, fortran, distutils on Intel Core 2 Duo, Mac OS X

[Erik Sherwood]

I'm trying to use numpy.distutils to compile fortran sources on a  
MacBook Pro Core 2 Duo machine, with python 2.4, scipy0.5.2, numpy  
1.0.1 (all installed using fink). I have g95, also installed with fink.

fortran is called using a call to numpy.distutils.core.setup

distutils goes into interactive mode, and I get the following error  
message/output:

Any ideas how to avoid this error?

It's not clear to me why gfortran is being used instead of g95. If I  
get a list of fortran compilers in interactive mode, I get

List of available Fortran compilers:
   --fcompiler=g95    G95 Fortran Compiler (0.90)
   --fcompiler=gnu95  GNU 95 Fortran Compiler (4.2.0)

What do I need to do to use g95 instead of gfortran?

Also, I had posted before about the problem of being taken to  
interactive mode when calling distutils.core.setup on Mac OS X. I  
believe there was a patch for 0.5.1, but apparently it wasn't  
included in 0.5.2. What needs to be changed to avoid interactive  
mode? (Or which subversion revision had the patch?)

Thanks,

Erik
