Guys, Just a note. After going through nightmares early on with kdelibs and kdebase pulling in Qt4 files, I have gotten trinity to build fine with Qt4 installed on arch. I'm not sure what has changed. Whether there were updates to cmake files that helped or whether it was not having kde4 installed that makes the difference. However, with Qt4 installed, I can now build trinity without conflicts. -- David C. Rankin, J.D.,P.E.
