Question

What do I need to do to get APC to work correctly, it seems I dont have a c compiler in the correct place or something similar to that? Also once it is install how do I verify that it is running correctly?

Looks like gcc isn’t installed. Depending on your release of Linux, the way to install gcc differs. I’m sure if you post which release you’re using, we’ll be able to help you.
