[HOpenGL] problems compiling hopengl

[chris]

well i have finally gotten around to trying to get hopengl to build
again. the pthreads problem i had before is gone now :). ok the problem
is after doing

./configure
gmake depend
gmake

this message happens

i am running freebsd 4.7 RC with ghc-5.04.1, mesa-3.4.2_2, and
green-card-2.04_1.

hints on how to fix?
