If you are interested in freebsd binary port then you are probably 
on your own as, if I am not mistaken, no scipy developer uses freebsd.
But getting scipy from CVS is not so complicated. See

  http://www.scipy.org/site_content/tutorials/CVSInstruct

I guess that freebsd has cvs software installed.

You should have seen the following message

    """
    DJBFFT (http://cr.yp.to/djbfft.html) libraries not found.
    Directories to search for the libraries can be specified in the
    scipy_distutils/site.cfg file (section [djbfft]) or by setting
    the DJBFFT environment variable."""

when building scipy but unfortunately this will not work as
scipy_distutils/system_info.py is still looking for a file
djbfft.a (not libdjbfft.a). You can try fixing this in system_info.py 
yourself, I'll later fix it also in CVS.
