The one we've been using on Solaris is a bit of a hack - in the install
step of building the xorg package, I do:

         -rm -f $(SDK_INCLUDES_DIR)/xorg-server.h
         sed -e 's%#define XF86DRI 1%/* #define XF86DRI 1 */%' \
             $(SOURCE_DIR)/include/xorg-server.h > $(SDK_INCLUDES_DIR)/xorg-server.h
