# DIR_DEPENDING_ON_XORG_VERSION in builder.sh has to be adopted (?)
# make sure libglx.so of ati is used. xorg.xorgserver does provide it as well
# which is a problem because it doesn't contain the xorgserver patch supporting
# the XORG_DRI_DRIVER_PATH env var.
# See http://thread.gmane.org/gmane.linux.distributions.nixos/4145 for a
# workaround (TODO)

# The gentoo ebuild contains much more magic..

# There is one issue left:
# /usr/lib/dri/fglrx_dri.so must point to /run/opengl-driver/lib/fglrx_dri.so
