[SciPy-User] curve_fit missing from scipy.optimize

It is Ubuntu 10.04 on an AMD-64 from the alternative install CD. I first

build-essential gfortran libatlas-sse2-dev
python-all-dev ipython

via apt-get. Then I installed nose, numpy and finally scipy using the
package from the website


 When I first installed it. Nose and numpy went through fine, but scipy
installation had some g++ problems, so I had to install a new g++. I tried
it out and optimize was screwed.

When that did not work, I installed 0.7.0 via the Ubuntu software center.
After that optimize worked, but curve_fit was gone. So back to 0.7.2 I went
to and optimize now worked, but curve_fit still did not.
