Figured the lbfgsb code might be better to use since it's the limited
memory version and it's an interface to the original fortran code.
But, I haven't had any success getting lbfgsb.fmin_l_bfgs_b to
work... (keep getting "failed in converting 15th argument `lsave'"
error)

That works much more nicely than attempting to modify the scipy code :)

Thanks,
