No, not at all. Scipy and Numpy all can be built and run on Cygwin.
And you do not need Atlas for this.
We do this for Sage: (http://www.sagemath.org).
http://trac.sagemath.org/sage_trac/wiki/CygwinPort
(right now it's not working as a whole, but things like scipy and
numpy certainly worked and  work)

certainly you would need a reasonably complete Cygwin development
toolset: compilers, make/autoconf, etc etc in order to do any serious
development on Cygwin.

If you are having problems figuring out what you need to install, just
install the whole thing =E2=80=93=E2=80=93 it's still a much smaller downlo=
ad than an
M$ Studio :=E2=80=93)
