I can't stand CPanel for a couple of reasons. One, it compiles everything (when it shouldn't on binary-package based systems). Two, it it integrates terribly into the system. Now, I will say that Ensim is terrible too and CPanel is much better than Ensim. But, there are better panels out there than CPanel.

As for CPanel and compiling, when you make that change, it does recompile CPanel. It doesn't take long, but it does.
