It turns out that cmake was not finding my freetype fonts. I installed them on my Mac via MacPorts and they are in /opt/local/share/fonts/ freetype-ttf, but I wasn't telling cmake about this location and it doesn't look there by default so it didn't find them so it turned off WITH_FREETYPE. For some reason that I can't fully explain, this ends up causing a crash when using the xcairo driver (maybe any cairo driver?). If I tell cmake where to find my freetype fonts (via - DPL_FREETYPE_FONT_PATH=...) and turn on WITH_FREETYPE, then I can use the xcairo device fine. I still don't know exactly why the workaround I first described prevented the crash, nor do I know what exactly changes with - DWITH_FREETYPE=ON, but now that it works, the priority of this already oddball configuration problem has gotten a lot lower IMHO.
