Hi All,

I haven't been able to reproduce trouble with matplotlib.  I've done a rebuild of \
fink from scratch without seeing the problem.

I can't reproduce this on my 10.4/ppc machine with unstable activated
(dateutil-py26-1.4-1 matplotlib-py26-0.99.0-1) and with all packages
built locally by fink (vs downloaded precompiled .deb).

The way this is *supposed* to work is that matplotlib detects that
dateutil is already present (as you found, it's a dependency) and
therefore does not build its own version of it. If matplotlib can't
find dateutil, it builds its own copy, which would collide with the
"real" dateutil package.

I assume your fink is building these packages locally (rather than
downloading .deb)? Look at the spewed output of the matplotlib build
and see what it says about detected support libraries. I get:

OPTIONAL DATE/TIMEZONE DEPENDENCIES
              datetime: present, version unknown
              dateutil: 1.4
                  pytz: 2008b
