can no longer build graphics/gle since glut was imported in base?

Hi,

since glut was imported in xsrc, and pulled up to netbsd-5, I can no longer
build packages like xscreensaver that depend on it.  graphics/glut grew a
builtin.mk file, hence graphics/gle no longer depends on the glut package,
but fails with:

checking for glutSwapBuffers in -lglut... no
configure: error: Cannot find required glut library
*** Error code 1
