Sorry about that. The new URL is http://www.scipy.org/Installing_SciPy
. The document has been fixed.

All of our FORTRAN code is FORTRAN-77.

I'm afraid that we don't have much in the way of Sun-specific
information, nor am I much familiar with the lay of the land, here. Is
the FORTRAN-77 support an optional install? Or is your version of the
compiler supposed to work without any extra libraries like f77compat
any more? If this is the case and you can figure out which version no
longer requires f77compat, we can put the appropriate check into
numpy. Please provide the output of "f90 -V".

Thanks.
