AWStats
From EpixStudios
AWStats is available through Gentoo's Portage.
emerge -av awstats
Once this is installed copy awstats.pl to the cgi-bin directory of apache. Configuration files are created in '/etc/awstats' by coying ths sample. AWStats will need to analyse your log files before you can see any results so you need to run the following command:
/var/www/localhost/cgi-bin/awstats.pl --config=sitename
You'll probably want this script to run at regular intervals, so add the line above to your crontab.
crontab -e
