[SciPy-dev] help on fortran compiler

Hi,
I am trying to build scipy v0.7.0 on SiCortex platform (MIPS64  
architecture on linux). However the problem is that the script does  
not recognize the pathscale fortran compiler I am passing..

The build step was

% python setup.py build --fcompiler=pathf95

After the build process proceeds for a while, I get..

:
don't know how to compile Fortran code on platform 'posix' with  
'pathf95' compiler. Supported compilers are:  
compaq,none,absoft,nag,gnu,sun,lahey,intelem,gnu95,intelv,g95,intele,int 
elev,pg,intel,mips,hpux,vast,ibm)
building 'dfftpack' library
error: library dfftpack has Fortran sources but no Fortran compiler  
found

How do I force the script to accept pathf95 since I have no other  
fortran compilers? Both BLAS and LAPACK have been built with  
pathscale and that is recognized in the build step.

II) I have a second issue once the fortran issue is resolved: we do  
not have dfftpack or umfpack built on our system. Does scipy build  
them, if not found in our library stack, so can I force the script to  
ignore dfftpack and umfpack?

Thanks for any help and suggestions.
