Upgrade from 1.0.1 to 1.1.0, not quite working

Hello everyone,

I've been struggling to get consistent animation results from Matplotlib
1.0.1. I am not entirely sure why I can get some programs to work, and
others not. The back-and-forth between the pyplot/pylab state-machine
approach and a more explicit object-oriented model gets me dizzy
sometimes.

I noticed that version 1.1.0 is taking an entirely new approach to
animations, with the animation module. Rather than invest more energy
in the old way of doing things, I decided to upgrade.

I downloaded the source, and built it as described here:

http://matplotlib.sourceforge.net/users/installing.html

I did not see any error messages during setup or install.

But when I started a Python shell, imported, and then printed
matplotlib.__version__, I got 1.0.1.

Must I explicitly uninstall the older revision somehow? I don't know
how to do this.

I suppose that I might have both versions installed, and that might be
useful if I have code that runs on the older version but not the new.

Alternately, is there a way to specify that 1.1.0 is now my default
version?

Thanks for any guidance and advice!

What platform are you using? How was 1.0.1 installed?

Something similar happened to me a few days ago. I followed this instructions

http://matplotlib.sourceforge.net/faq/installing_faq.html#how-to-completely-remove-matplotlib

to completely remove matplotlib, and then I rebuilt the latest
version from source.
