I have a low-level access module to ODRPACK.  One thing to note is that I
have it setup so I can use Python, C, or Fortran functions in ODRPACK. I'm
in the process of generalizing this into a separate module so I can use it
with other libraries.  I will put it up for ftp soon (probably sometime
next week).  ODRPACK itself is available from netlib.

PS: A short blurb on ODRPACK from it's readme file:

 *** INTRODUCTION

 ODRPACK is a portable collection of Fortran subprograms for fitting a model to
 data.  It is designed primarily for instances when the explanatory as well as
 the response variables have significant errors, implementing a highly
 efficient algorithm for solving the weighted orthogonal distance regression
 problem, i.e., for minimizing the sum of the squares of the weighted
 orthogonal distances between each data point and the curve described by the
 model equation.  It can also be used to solve the ordinary least squares
 problem where all of the errors are attributed to the observations of the
 dependent variable.  File CHANGES identifies how the current version of
 ODRPACK differs from earlier releases.
