hello i wrote this to the mailing list long ago and somebody wanted to fix it. as things turn out, he forgot about it :) i post it here now to keep it pending. xorg-server 1.9.0 is out and still needs --with-dri-driver-path to find the dri modules though there is dri.pc. please let us get rid of this very long option before xorg 7.6 is out ;) many thanks!
I submitted a patch to the xorg-devel list for review.
This was fixed today by git commit c36ca7b1862ecd86df089f4e1933379a113928ea.
