[Matrix-SIG] Nonlinear optimization routines anyone?

does anybody has neatly packaged nonlinear optimization routines
implemented in NumPy? I'd like to have either conjugate gradients or
BFGS. Explicitly calculating the Hessian is out of question (because
of the size and complexity of the problem). 

I thought translating part of the matlab codes of C. T. Kelley
(http://www4.ncsu.edu/eos/users/c/ctkelley/www/matlab_darts.html) to
Numerical Python unless something already implemented emerges.
