did you remove X11 off your system? or did you (or Macports automatically) try to change out x.org files? Does your X11 still function correctly? open up Terminal and type in... Code: /usr/X11/bin/glxgears if X11.app fires up right, and you get a window showing colored gears spinning... then your X11 and OpenGL are working fine. if they are.. compiling it right and setting dyld_fallback should get it to work, so not sure what else to tell ya.
