Someone knows how to install trac on Plesk 8 based CentOS 4.3 ?

What packages I need to install?

What I need to add in vhost.conf for the domain who has trac ?

If you've added Dag's repository you can yum install trac mod_dav_svn. After that empty /etc/httpd/conf.d/trac.conf (as it sets up a server-wide trac and uses a slower CGI setup instead of mod_python) and put your config in vhost.conf.
