We still require only gtk 2.2, and consequently carry around some extra 
chunks of code to support versions before 2.4. Can we drop this and 
require 2.4 or later? Or possibly even a later version? It looks like 
2.4 came out in the fall of 2004.

I've found pyparsing rather brittle between revisions in the past, hence 
the desire to have a local copy. I don't know if recent versions have 
stabilized -- given that we have something that works, I'm not too keen 
on tinkering with it. 
Not knowing much about packaging myself, I think Debian should only go 
forward with using an external dependency if an *exact* version of 
pyparsing can be specified, rather than >=. Or at the very least, if a 
different version of pyparsing is applied, one needs to make sure that 
the mathtext examples all pass unchanged.

We've just receive this bug report about the internal copy of
pyparsing included in mpl.
The situation in Debian is:
Stable 	 1.5.0-1
Testing 	1.5.1-2
Unstable 	1.5.2-1
Currently mpl ship:
$ grep "^__version" lib/matplotlib/pyparsing.py
__version__ = "1.5.0"
__versionTime__ = "28 May 2008 10:05"
In the changelog I can see:
$ egrep -A2 "2007-11-09.*pyparsing" CHANGELOG
2007年11月09日 Moved pyparsing back into matplotlib namespace. Don't use
 system pyparsing, API is too variable from one release
 to the next - DSD
So there seems to be a reason for this "private" copy. The question
is: is this reason still valid nowdays? should we (at least packagers)
remove the private copy and rely on the system pyparsing (or at least
introduce a "check if system has pyparsing, if not fallback on
private" wrap)?
I haven't checked, but maybe you already know the answer :)

The axes_grid examples, broken by the recent spine patch, are now
fixed in the svn.
Also, when I commit axes_grid toolkit into the trunk, I deleted a few
example under examples/pylab_examples. For example, axes_divider.py in
the error message below has been deleted.
IOError: [Errno 2] No such file or directory: 'axes_divider.py'
The doc build script somehow still try to run those script. I'll try
to look into what's going on later. If others know any trivial
solution, please go ahead and fix it.

If you can coerce the recipe I sent this list on May 20 for running the
unit tests to run these as well, we'll see these sooner. Furthermore,
I've been busy with the spines, but I think we should check in new
baseline images in the test suite so that the builtbot waterfall goes green.

I was just updating the site docs and a few examples are failing to
build. Some of these are easy pickens, so if you have a quick fix,
please put it in, and reply here when you've fixed one to avoid
duplication of effort.

I just did a quick read through of the spine code and example, and
have two minor comments.
You do an isinstance(arg, basestring) to check for string input.
Typically, we encourage cbook.is_string_like to have a central point
of maintenance and consistency for these checks.
Also, in the example, you appear to turn off a spine by setting the
color to 'none'. My thought it would be more natural to use the
"visible" artist property here (or at least support both)
 @allow_rasterization
 def draw(self,renderer):
 "draw everything that belongs to the spine"
 if not self.get_visible() or self.color.lower()=='none' or not
self.color:
 # don't draw invisible spines
 return
 self.artist.draw(renderer)
Also, I think the class of strings representing "no color" in mpl is
larger -- it should also include self.color.lower()=='none' and the
empty string, which I've included in the example code.
