I setup trac 0.11dev last night on CentOS 5 to manage the review process for our book, using svn 1.4.5 and python 2.4.3. It was very nice! The new admin interface is great, and allows you to easily load plugins:
One gotcha, that I always forget is, if you setup tracd running behind an Apache rewrite you need to setup the trac.ini file to have both:
base_url = http://trac.example.com use_base_url_for_redirect = True
And your rewrite stanza should look like this:
ServerAdmin email@example.com ServerName trac.example.com RewriteEngine on RewriteRule ^(.*) http://192.168.1.1:8000$1 [P]
Just a note, it is not 100% beta yet, but from the traffic on the list, it appears it should be beta any day now. Nice work Trac team…this rocks!
