I don't think we have one.
But it is almost trivial
1. Disable all stuff you do not need (ICP, snmp, htcp)
2. Install two Squids with different prefix
3. Set http_port differently in each instance.
If using the same binary things gets a little trickier
2. Create two configuration files,
3. Set http_port, cache_dir and log paths differently in each instance
4. Start both Squids. Watch cache.log for complaints and fix the source of the complaints, if any.
