I recently got CalDAV working under Linux (I have to look into getting 
CardDAV setup soon) but since they're similar hopefully my workarounds will 
work for you too! I'm guessing that most of what I've posted below should 
work just by substituting caldavd for carddavd when necessary.

Installation worked (mostly) for me but I used a system install (-i):
$ ./run -i /opt/CalendarServer

First thing you'll want to do is setup some default configs:
$ rm -rf /opt/CalendarServer/usr/caldavd/caldavd.plist
$ cp conf/servertoserver-test.xml 
/opt/CalendarServer/etc/caldavd/servertoserver.xml
$ cp conf/accounts.xml /opt/CalendarServer/etc/caldavd/accounts.xml
$ cp conf/caldavd-test.plist /opt/CalendarServer/etc/caldavd/caldavd.plist
$ cp conf/sudoers.plist /opt/CalendarServer/etc/caldavd/sudoers.plist
$ chmod 600 /opt/CalendarServer/etc/caldavd/*

There are two bugs on Linux [1] [2] that result in in the Twisted extensions 
being installed to the wrong place on 64-bit systems, resulting in an error 
similar to what you're describing - are you on x86_64 by any chance?

To fix the x86_64 bug, run:
mv ../lib/python2.6/site-packages/twisted/plugins/caldav.py* 
../lib64/python2.6/site-packages/twisted/plugins

As for the PYTHONPATH bug, you'll need to modify the PYTHONPATH variable set 
in /opt/CalendarServer/usr/bin/caldavd and include the "site-packages" 
folders inside your CalendarServer installation directory as well as the 
system packages. For reference, mine looks like this:

PATH="/usr/bin:$PATH"
DESTDIR=/opt/CalendarServer
PYTHONPATH="/usr/lib/python2.6/site-packages/:$PYTHONPATH:$DESTDIR/usr/lib/python2.6/site-packages/:$DESTDIR/usr/lib64/python2.6/site-packages/"

I've added $DESTDIR to make it easy to change later should I decide to move 
my CalendarServer installation out of /opt. If you're using x86, then forget 
the last part with the lib64 (":$DESTDIR/usr/lib64/python2.6/site-packages/")

I have a little script "run.sh" that I use when testing:

#!/bin/sh
/opt/CalendarServer/usr/bin/caldavd -X -f 
/opt/CalendarServer/etc/caldavd/caldavd.plist -T 
/opt/CalendarServer/usr/bin/twistd

That starts CalendarServer forcing the use of the CalendarServer-patched 
Twisted with config file /opt/CalendarServer/etc/caldavd.
