setup.py can not install due to incorrect module name

I obtained the development version of CairoPlot and tried to run:

sudo python setup.py install

but got an error msg:

running install
running build
running build_py
file CairoPlot.py (for module CairoPlot) not found
file CairoPlot.py (for module CairoPlot) not found
running install_lib
warning: install_lib: 'build/lib.linux-x86_64-2.6' does not exist -- no Python modules to install
running install_egg_info
Writing /usr/local/lib/python2.6/dist-packages/Cairoplot-1.1-py2.6.egg-info

This is because the file is cairoplot.py, not CairoPlot.py. Because Python generally uses lowercase for module names, I changed the setup file to use the lowercase "cairoplot" instead of changing the filename. I was then able to install cairoplot. The diff is attached.
