You do not need to reinstall squid, the version in K12LTSP includes the
delay pools feature.
Note that the document you linked to is from 2001. That is ancient, much of
it will not apply to a recent Linux distro (kinda like using Windows 3.1
documentation to work on Windows XP)
As for configuring delay pools, it is pretty well documented in squid's
example config file: /etc/squid/squid.conf.defaults
Here is a simple example that you can append to /etc/squid/squid.conf
delay_class 1 2
delay_access 1 allow all
delay_parameters 1 -1/-1 8000/8000
What this does is limit all users going to all web sites to a maximum
of 64kbps. See the additional examples in /etc/squid/squid.conf.defaults
if you want to do something more complicated.
