This is indeed spooky, but not the problem.  mzscheme looks for a compiled 
version of gl-prims (.zo or .so) before looking for the .ss version.  The 
compiled version (gl-prims.so) is generated from gl-prims.c.

I fixed the problem - gl-unsafe.ss was trying to get its primitives from 
gl-prims instead of gl-prims-unsafe - and exp tagged it, so if you're using 
the CVS version you should be fine.  Otherwise you'll have to wait for the 
package to be recompiled and put on the web page, which I suspect will happen
