Hmmm... If I'm not mistaken, RHEL installs the squid binary by default
as /usr/sbin/squid. I'd be willing to bet that's the version that the
startup script is utilizing. That Squid was compiled to use a different
conf file (/etc/squid/squid.conf). I imagine that it's logging to
/var/log/squid/*.log.

So, you have three choices. From simplest to most complex...

1) Disable the Squid service from starting ("chkconfig squid off" on the
command line is one method). Then edit /etc/rc.local and add the
"/usr/local/squid/sbin/squid -NCd1" (without quotes) as the last line.
This will start your new Squid with the server.
2) Edit /etc/init.d/squid, and replace every instance of /usr/sbin/squid
with /usr/local/squid/sbin/squid. This should use the native startup
script to manage the new Squid.
3a) Recompile Squid from source to replace the RPM version. Run
/usr/sbin/squid -v to get the compilation options of the RPM version
(the list will be long, and will have some repeated arguments). Pay
close attention to the last instance of any *dir options (bindir,
sbindir libexecdir, etc). Recompile Squid with the options you selected
feel beneficial, and the *dir options from the RPM.
3b) Grab the Fedora 6 SRPM (squid-2.6.STABLE9-1.fc6.src.rpm) and build it.

Hopefully the options outlined above are clear enough. If not, feel
free to ask more questions.
