I've used pacman on Arch to install xorg-server and Qt5, but keep running into "display not found issues" or "qmlviewer cannot connect to x server" when running xhost and qmlviewer respectively.

The X11 server appears to work (I can run Xterm), but I suspect I'm taking the wrong approach to building Qt on my Pi... Do I actually need an X server to run Qt on Pi? I keep reading about how QTonPi bypasses X based rendering...

Should I uninstall xorg-server, Qt5 and attempt to build QTonPi, or can I "patch" my current installation?
