[SciPy-user] GCC 3.3 requirement

[Humufr]

One big problem with gcc4, especially 4.0 is that gfortran is buggy. A 
lot of improvement has been done but in compariason with commercial 
compiler or g95, it's not the same things. gfortran is an alpha version 
of a true fortran 90 compilers. So many things in scipy are using 
fortran so this is a critical issue for the moment.
