Can't install CVS version

[Christopher Kalos]

	Because we're trying to stick with 2.2 for now, I downloaded the 2.2
release via horde.org's CVS, and am currently working on setting it up.
Right now, I'm stuck at this:

Fatal error: HordeSession is already a function or class in
./templates/setup/session.lib on line 92

It shows up when accessing horde/setup.php3, so I can't even get to
configuring horde, let alone testing it.  Are we missing anything for phplib
that horde now needs?  Did I just neglect to notice where else HordeSession
is being established?

Thanks in advance,
CK
