When jasper is emerged while opengl is set to nvidia I get the following error messages. /usr/lib/opengl/nvidia/lib/libGLcore.so.1: undefined reference to `_nv000016gl' followed by several just like it with just what nv value is an undefined reference changing. followed by. collect2: ld returned 1 exit status. After searching the forums I found the following. eselect opengl set xorg-x11 env-update emerge jasper eselect opengl set nvidia env-update I was able to emerge jasper when I followed said instructions. So it is something with jasper and the nvidia opengl that is stopping the compile. Until this is fixed I suggest that some sort of message on failure of the compile referencing this problem be put in the ebuild.
