I think this may be more of a Mac x11 issue than a ROOT issue, but after I install ROOT and try to run it I get the following error message:
dyld: Library not loaded: /usr/X11/lib/libfontconfig.1.dylib
Referenced from: /usr/X11/lib/libXft.2.dylib
Reason: Incompatible library version: libXft.2.dylib requires version 5.0.0 or later, but libfontconfig.1.dylib provides version 3.0.0
I’m running on OS X 10.5.8 and I have the same problem if I’m installing the mac binary or compiling from source.
