But I can reliably say that XQuartz installs its files in /opt/X11, and that it should not be hard for the configure script to detect that location.

IIRC, /usr/X11R6 is populated with stubs that get filled in when the (no longer available) optional X11 package was installed. XQuartz conveniently also installed in that same directory. I think future versions of XQuartz will have to install in /opt instead.
