Try editing matplotlib/texmanager.py and replacing the < with <= in
the following code; it should read
if vers<='1.6':
# hack the alpha channel as described in comment above
alpha = sqrt(1-X[:,:,0])
else:
alpha = X[:,:,-1]
also, print the version number and let us know what you have.
Make sure you rm -rf the ~/.matplotlib/tex.cache after reinstalling.

I made the change and that fixed the problem. The output of dvipng --version is below.
Thank you very much.
I assume that the fix will be in the cvs version?
One more question. Even though I have my rc file set to use type1cm font
font.latex.package : type1cm
It uses an non latex font for on screen display. The saved version of the plot uses
a latex font but the latex font is always serif regardless of the font.family setting.
How do I get the onscreen display and the file saved to use the serif version of the typelcm font?
