Just installing Chaco and the stuff it depends on can actually be somewhat
easier than matplotlib: we don't bother with external libjpeg, libpng, and
libfreetype libraries. The major issue would actually be disabling building of
TVTK if you don't have VTK installed and you only care about Chaco, but even
that's a comment-out-one-line operation.

In the coming weeks, though, we will be playing around with a reorganization of
the repository along the lines of the scikits layout if you've been following
that conversation. That would enable one to just build the enthought subpackages
that you need, or allow easy_install to do so. Even if we don't end up
reorganizing the trunk that way, we'll probably have such a reorganized mirror
of the trunk using svn:externals to get the same effect for distribution purposes.
