[SciPy-User] Error when trying to use scipy.optimize.fmin

[Astier Frank]

Hi - 

I'm trying to use fmin from scipy.optimize, and I get the following error. My machine is a MBP with MacOSX 10.6.7. I'm running the example below with the system's Python 2.6.1, which is a universal binary supporting 3 architectures (see below). I got scipy from the superpack maintained by Cristopher Fonnesbeck, who couldn't reproduce and has never seen that for any other user... Any idea??
