Hmm, I'm afraid I'm not able to help you here, as I'm not sure the 6.8.2
dri layer is 64 bit clean and compatible with 6.8.2, and I have no 6.8.2 I
can compile and test with. I think you have to settle with 6.9 if you want
a working 64-bit dri.

The only advice I can give is to really make sure you made a "make clean"
before recompiling for 6.8.2.
