pytz, dateutil, subprocess installation

Hi,

I've seen nothing about installing pytz, dateutil that are usefull for
matplotlib-users. In mandriva I think that this 2 packages are not yet in any
package. What is the common way to include them? (any one can point me for
example to a fedora rpm spec file that does the work??)

I have a directory named /usr/lib/python2.4/site-packages/pytz/zoneinfo that
is included in python-matplotlib package but no module pytz so that
date_demo*.py examples don't work.
