I had the same error, and apparentely autotools will refuse to detect it correctly if it's not installed in /usr. 2) Try specifying manually paths to Qt3 in your ./configure (--with-qt-dir= option if I remember correctly). For building trinity, check out arch PKGBUILDs in our git tree. They are pretty much bash scripts with some variables used by pacman to create binary packages. What you need to look at is the build() function.
