I'm just trying to get this to run but there isn't very good documentation out there.
I did the RPM route, the Tar bz gave me issues. The RPM seemed to install everything properly and sarg is in the etc folder.
Somewhere I was told once you set everything up you enter:
192.168..... (Whatever your servers ip is)/squid-report
That did not seem to work...
The how to txt file on the sarg site is lacking in details.
