Scipy 0.7.0 on Ubuntu Lucid Lynx with Python 2.6.5.

At the top of diffev.py's solve() method is a loop that runs per
generation of the genetic algorithm, you might consider placing a
"print gen" statement there to see if it is running or stuck somehow.
The virtual server I'm using has 4 CPUs so I plan to run the
distribution fitting in parallel. Here are current timing results
fitting both loc and scale, in parallel these would have taken 207
seconds (gamma time):
distribution: powerlaw took 69.5095369816 seconds to run
de parameters [ 1.31332767 0.55933617 2.45766383]
nnlf: 23.3610045864
distribution: beta took 47.2591450214 seconds to run
de parameters [ 0.70567183 0.6011756 0.607 2.41 ]
nnlf: 7.45846316363
distribution: gamma took 206.991358995 seconds to run
de parameters [ 1.40727512e+02 -5.83784812e+00 5.55091421e-02]
nnlf: 26.7597491247
distribution: pareto took 86.9141609669 seconds to run
de parameters [ 7.75987131e+13 -1.05369726e+14 1.05369726e+14]
