It's suppose to. So for some reason the Make file isn't updating the wacom_drv.so. Interesting. I wonder if that's due to the patch. So you need to use the copy command:
Main "error" was that I thought that driver is updated when I write: sudo make install.
sudo cp /xf86-input-wacom-aa95e13/src/.libs/wacom_drv.so /usr/lib/xorg/modules/input/wacom_drv.so
Right the Xorg dev. Peter dropped wacomcpl, wacdump, and xidump from xf86-input-wacom. He feels those are user land programs and don't belong ina driver. I gather it was a bit of a struggle to convince him to include xsetwacom, which he had to rewrite. So that's part of the problem, xsetwacom only really matured for xf86-input-wacom with 0.10.8.
I don't believe you could ever put a double click on a stylus button. Basically for a scroll or something like that you want to use Tom Jaeger's EasyStroke program.
