After upgrading to X11 ver 0.2 for Mac OS X (using 10.2.4), I get warnings about multiple definitions of opengl symbols. This did not happen with version 0.1. It seems to find the open gl libaries in both /usr/X11R6/lib and in /System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/. Graphics seem to work fine. Should I be worried? Thanks, Peggy
