This may be a problem that bit me awhile ago. If so, it was a bug in 
py2app that has since been fixed.

I suggest you install the most recent version of py2app. I also suggest 
you install matplotlib 1.0.1 (I believe you said you were using 1.0?) 
using the binary installer; that will give you a fresh pytz.

If you really want to play it safe:
- Save an archived copy of your site-packages, just in case
- Throw away dateutil, pytz and matplotlib and pylab
- Edit easy_install.pth and remove any mention of these packages 
- Install a new matplotlib from the Mac binary; this should give you 
fresh copies of all these
