I installed CollabNetSubversion-client-1.6.17-1.x86_64.rpm, which installs httpd v2.2.19
# /opt/CollabNet_Edge/csvn/bin/httpd -v
Server version: Apache/2.2.19 (Unix)
I installed Trac-0.12.2.tar.gz.
On the Apache httpd that comes with RHEL5, which is running v2.2.3
# apachectl -v
Server version: Apache/2.2.3
I installed mod_wsgi, since that is what the trac website recommended.
python.conf settings for the 2.2.3 httpd:
Alias /trac/chrome/common /var/trac/htdocs/common
Alias /trac/chrome/site /var/trac/htdocs/site
<Directory "/var/trac/htdocs">
Order allow,deny
Allow from all
</Directory>
LoadModule wsgi_module modules/mod_wsgi.so
WSGIScriptAlias /trac /var/trac/cgi-bin/trac.wsgi
<Directory /var/trac/cgi-bin>
SetEnv PYTHON_EGG_CACHE /tmp
WSGIApplicationGroup %{GLOBAL}

I setup a trac project and configured it to point to an existing SVN repository.
The first error reported in trac.log was:
ImportError: No module named svn
http://trac.edgewall.org/wiki/TracSubversion#Troubleshooting has the answer, so I added symbolic links to the bindings that are in the CollabNet area:
cd /usr/lib64/python2.4/site-packages
ln -s /opt/CollabNet_Edge/csvn/lib/svn-python/libsvn .
ln -s /opt/CollabNet_Edge/csvn/lib/svn-python/svn .
Next error in trac.log (thanks for reading this far -- this is the real problem):
Trac[svn_fs] INFO: Failed to load Subversion bindings

I found this page that speaks of the same problem: http://subversion.open.collab.net/ds/viewMessage.do?dsForumId=3&dsMessageId=313639
The advice given: "you probably need to use our Apache server or update yours to 2.2.11" (i.e., 2.2.19 to match the one in the CollabNet package). Well, the CollabNet-bundled httpd server doesn't have mod_wsgi installed, and I'm not sure how I could build such and add it to their server -- so I don't like that option. I'd rather not update our main httpd from 2.2.3 to 2.2.19 -- but is this really my only other option?
BTW, I tried downloading SVN 1.6.17 and building and installing swig-py -- to build the bindings, hoping to use them with the 2.2.3 httpd and trac. However, I'm not sure this is safe/correct... SVN is tied to the 2.2.19 httpd, somehow, right? Anyway, I couldn't get that to work either. Any advice appreciated.
UPDATE: Following Graham's suggestion, I compiled a 2.2.19 httpd server (to replace the RH5 2.2.3 httpd) and now everything is working. My first attempt with the 2.2.19 httpd failed. I had to configure httpd with option --with-included-apr, then everything worked.
