Trac
There are many issue tracking systems out there, but if you are working on any software projects you'll probably want one. This guide focuses on using Trac, since it integrates nicely with php and mySQL. First check your /etc/portage/package.use file to enable the following USE flags:
www-apps/trac subversion mysql -sqlite
Next we will need to emerge trac and the apache2 mod_python module.
$ sudo emerge -av trac mod_python
Change the apache2 config file
$ sudo nano -w /etc/conf.d/apache2
And ensure the APACHE2_OPTS variable contains the directive
-D PYTHON
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
