/compat/linux/usr/X11R6/lib/libGL.so.1 installed by graphics/linux_dri is overwritten by installation of x11/nvidia-driver. Fix: I do not know how to manage this problem. graphics/linux_dri is required by math/mupad. and I use nVidia video card. only about my host, linux_dri can be removed as reading Dependency in the Makefile of mupad. but the confliction might occur by other ports. How-To-Repeat: install one after installation of the another.
