ROOT install in Mac OS X Mountain Lion


I’ve recently installed the binary distribution of root 5.34.01 for Mac OS X Mountain Lion. Xquartz 2.7.2 is also installed. However, every time I try to launch root I get a dialog box telling me I need to install X11. I wonder what am I missing. Thanks in advance,

It seems I only needed to post the question here to get the solution by myself. I’m sorry. I succeeded by adding /opt/X11/lib:/usr/X11/lib to DYLD_LIBRARY_PATH.
