Comment 91 for bug 282387

I'm stuck at the 4th step in the sequence:
sudo apt-get build-dep xserver-xorg-input-evdev
apt-get source xserver-xorg-input-evdev
cd xserver-xorg-input-evdev-2.0.99+git20080912
patch -p1 < /path/to/preinit.diff
./autogen --prefix=/usr
make
sudo make install

I get the following error:
laptop:~$ patch -p1 < /path/to/preinit.diff
bash: /path/to/preinit.diff: No such file or directory

I'm running: Intrepid 8.10 64 bit kernel 2.6.27-12 generic Gnome 2.24.1
Any help appreciated!
