Does anybody have any experience of installing the latest apache from the source on a raq4i?

Ive read the instructions found in posts about the RAQ3, does anyone know if these work okay for the RAQ4 ?

What do people think of running two copies of apache ?

The cpanel only operates on port 81, what if I installed a new copy of apache and made it run on port 80, and leave the old one on port 81, do you think that would work.

Any ideas anyone ???
