I am trying to compile scipy svn (r1676) with gcc 4.1.  One of gfortran's 
developers suggested me to use gcc 4.1 instead of 4.0.2 because this release 
is supposed to be much more stable and fast.

After building numpy successfully, also from svn, the scipy compilation fails 
when tries to build the dfftpack library.  It seems that distutils fails to 
find the fortran compiler.  I'm a bit perplexed about this because it has 
been able to build all the previous fortran subpackages...

I am not specially interested in building scipy with gcc 4.1 but I thought 
that the resoults would have some interest.
