I had a good go at this, otherwise my new i7 will be idle
Had to modify config file thus (it didn't like custom)

Next, distcc has altered, you define how many threads each can handle, new guide is here
https://wiki.archlinux.org/index.php/DistccCan't get this working (yet), logs on i7 look like this
