	# We can do two things here, and neither of them is very nice.

	# For direct rendering libGL has to be able to load one or more
	# dri modules (files ending in _dri.so, like fglrx_dri.so).
	# Gentoo's mesa looks for these files in the location specified by
	# LIBGL_DRIVERS_PATH or LIBGL_DRIVERS_DIR, then in the hardcoded
	# location /usr/$(get_libdir)/dri. Ati's libGL does the same
	# thing, but the hardcoded location is /usr/X11R6/lib/modules/dri
	# on x86 and amd64 32bit, /usr/X11R6/lib64/modules/dri on amd64
	# 64bit. So we can either put the .so files in that (unusual,
	# compared to "normal" mesa libGL) location or set
	# LIBGL_DRIVERS_PATH. We currently do the latter. See also bug
	# 101539.

	# The problem with this approach is that LIBGL_DRIVERS_PATH
	# *overrides* the default hardcoded location, it does not extend
	# it. So if ati-drivers is merged but a non-ati libGL is selected
	# and its hardcoded path does not match our LIBGL_DRIVERS_PATH
	# (because it changed in a newer mesa or because it was compiled
	# for a different set of multilib abis than we are) stuff breaks.
