Hi
I use kubuntu 9.10 and downlaoded ati driver then after this command:
fakeroot sh ati-driver-installer-9-6-x86.x86_64.run --buildpkg Ubuntu/karmic

I saw these messages:

Package build failed!

Looks like you don't have cdbs installed.

and what's this message?(after this command : sudo m-a a-i fglrx)

Processing triggers for initramfs-tools ...

Package fglrx-kernel-source not installed?
Running "m-a -f get fglrx-kernel-source" may help.

So, did you run the command the error message suggested?
