Mesa source doesn't seem to include this fix:

http://freedesktop.org/cgi-bin/viewcvs.cgi/mesa/Mesa/src/mesa/drivers/dri/c=
ommon/depthtmp.h?r1=3D1.4&r2=3D1.5

=46rom the commit log you said:

'Don't compile WriteMonoDepthSpan if HAVE_HW_DEPTH_SPANS is defined --=20
it won't be used in that case, and it wanting WRITE_DEPTH was making=20
r128 die on the undefined symbol.'
