Trac

first we will need to emerge trac and the apache2 mod_python module

sudo emerge -av trac mod_python

now we will need to change the apache2 config file

sudo nano -w /etc/conf.d/apache2

and add

-D PYTHON

to the APACHE2_OPTS line. next we will need to setup trac. simply go with defaults

sudo trac-admin /var/lib/trac/my_trac initenv

next we will need to set directory permissions on the appropriate files and folders.

sudo chown -R apache:apache /var/lib/trac

sudo chown -R apache:apache /var/www/localhost/htdocs/trac

now we set up the trac to use our default svn authorization file for connections and restart apache.

sudo nano -w /etc/apache2/modules.d/16_mod_python.conf
