iam following  these steps :
1) cd ~
2) sudo bash
3) git clone git://github.com/kohler/click.git
4) git clone git://github.com/kohler/click-packages.git
5) cd /usr/src/linux-headers-2.6.24.7-generic
6) patch -p0 -b < /home/niko/click/etc/linux-2.6.24.7-patch

At this step i have the error that is below :

Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
