I guess you're providing an input data with a wrong shape.
 aa = np.transpose([listA, listB, listC])
 plt.hist(aa, bins=4, histtype='bar',
alpha=0.75,rwidth=0.85,label=['A','B','C'])

you need to install the development package (in the common sense, for
your pacakge manager) to be able to compile code that dinamically
links to libz. For example on Debian with libz-dev (provided by
zlib1g-dev).
Install a similar package for your distrivution and try to recompile matplotlib.

I forgot to CC the list :S
and I updated to svn trunk and it now works fine :)

The linked page below shows how you put the legend above the graph.
http://matplotlib.sourceforge.net/users/plotting/legend.html#legend-location
You can put it below the axes by adjusting the bbox_to_anchor parameter.
Try something like
 bbox_to_anchor=(0., -0.1, 1., -0.1), loc=1
Make sure to adjust the suplot parameter (or axes location) to make
enough room for the legend.

How do you show the legend below the graph, so it doesn't overlap at
all with the graph? The docs for the legend() "loc" parameter only
seem to specify where *on* the graph you want it to show, which is
driving me nuts because even using "best", it usually hides some of my
data.
I want to see *all* of my graph, as well as the legend. Is there any
way to do this with pylab?
Any help is appreciated.
