The current ~x86 xscreensaver ebuild do not find the OpenGL Libraries (provided by nvidia-glx) and therefor does not build the OpenGL based savers, like glmatrix. Could be an issue with nvidia or with xscreensaver, the later on prompts during configure: ################################################################# Warning: Use of GL was requested, but it was not found. More specifically, we found the headers, but not the libraries; so either GL is half-installed on this system, or something else went wrong. The `config.log' file might contain some clues. Those demos which use 3D will not be built or installed. You might want to consider installing OpenGL and re-running configure. If your vendor doesn't ship their own implementation of OpenGL, you can get a free version at <http://www.mesa3d.org/>. For general OpenGL info, see <http://www.opengl.org/>. ################################################################# config.log will be appended. nvidia-glx is installed at most recent version and OpenGL generally is available, as glxgears runs at expected speed.

You're using nVidia drivers? /usr/lib/libGL.so: undefined reference to `_nv000038gl' /usr/lib/libGLcore.so.1: undefined reference to `_nv000037gl' Try switching to xorg-x11 OpenGL.
Switching to xorg-x11 does not affect the outcome, still the same error message printed. Adding xorg-x11 config.log.

X11-drivers: any idea about broken symlinks?
And for a quick fix, kann I simply re-link to the nvidia libs?
After removing that stale links and running "eselect opengl set nvidia" once more, fresh correct links were created. Everything is back to functional, maybe a side effect of some installation issue. Worksforme.
what broke this in the first place?
