Great!
But you should certainly use the CVS version of scipy for that
as recent changes in CVS have made packaging scipy much easier.
See also PACKAGERS.txt (that I'll soon update again).

That is weird as acosh is defined in fastumath_unsigned.inc.
Try using -UHAVE_INVERSE_HYPERBOLIC.
Let us know if it works or you found another solution for freebsd.

You have to follow installation instructions in

  http://cr.yp.to/djbfft/install.html

Yes, they are a bit braindead but "fixing" djbfft installation process 
is not so simple.
