Thanks for reminding me of this exteral dependency.It is indeed true:
http://nielsmayer.com/xwiki/bin/view/Exhibit/Presidents4 is broken. It uses
the trunk exhibit directly, see xwiki zip source for details:
http://nielsmayer.com/xwiki/bin/download/Exhibit/Presidents4/Presidents4Pkg.xar.

The "Podmap" view in
http://nielsmayer.com/xwiki/bin/view/Exhibit/NPRpods3 (work
in progress) is also even more broken than it was before.
What is interesting is that there is a dependency on painter even in a case
where nothing to be "painted" -- instead, the colored links in the
color-legend are all broken, as are
the  circle-of-color links in the map. The shadows of the missing
circle-of-color display faintly in the background. The image contains a
broken link to e.g,
http://service.simile-widgets.org/painter/painter??renderer=map-marker&shape=circle&width=20&height=20&pinHeight=5&background=A97838,
 returning code 503: Service Temporarily Unavailable.

Clearly, it is non-optimal to be using external images just to paint colors.
And why not have the browser render images sized appropriately directly,
rather than using an external service?

Note that when other views render into this color-legend area, e.g. timeline
and timeplot, they are rendered correctly as HTML boxes-of-color rather than
images-of-color. Here's
what happens when timeline renders correctly, whereas map renders a
(currently broken) painter image:
