Please also try on PPC OS X 10.4, 10.5, and 10.6, and also Intel OS X
10.4, 10.5, 10.6, both 32 and 64-bit, then report back.
That's what the Sage fortran spkg handles.

I oscillate in my hopes about cygwin... There are other approaches to
Sage on Windows, e.g.,:
http://windows.sagemath.org/
Regarding fortran, for a "Microsoft Visual C++" version of Sage, I
will just get rid of Fortran (and Lisp) entirely, and not bother with
building anything currently in Sage that depends on them...

Fortunately this is not true anymore. See
http://cygwin.com/ml/cygwin-announce/2009-12/msg00027.html
where it says "- Multiple Cygwin installations can co-exist on a
machine, as long as you keep them separate.".
