Andreas,

I've had good luck with the optimization package from the Forest Service:
http://www1.fpl.fs.fed.us/optimization.html.  I turn my least-squares
problems into single function minimization problems (sum the squares of the
errors) and call Uncmin_f77.optif0_f77.  For some reason this has worked out
better than my previous efforts in FORTRAN using the LM code SNLS1E.  Watch
out for the 1-based indexing.
