[ltp] building thinkpad-source on debian

[Justin Georgeson]

I have a 600X-5EU-2645 running debian unstable. I want to bulid the 
thinkpad-source package to get access to all the power saving features. 
I'm running kernel-image-2.6.4-1-686, and have these kernel packages 
installed:

kernel-doc-2.6.4           2.6.4-1
kernel-image-2.6.4-1-686   2.6.4-1
kernel-package             8.086
kernel-source-2.6.4        2.6.4-1
linux-kernel-headers       2.5.999-test7-bk-15

I copied /boot/config-2.6.4-1-686 to 
/usr/src/kernel-source-2.6.4/.config and ran `make oldconfig`. Then I 
run `make-kpkg --rootcmd=fakeroot modules-image` as instructed in 
/usr/share/doc/thinkpad-source/README.Debian, and get this:

make[1]: Entering directory `/usr/src/modules/thinkpad'
fakeroot /usr/bin/make -w -f debian/rules binary-modules
make[1]: fakeroot: Command not found
make[1]: *** [kdist_image] Error 127
make[1]: Leaving directory `/usr/src/modules/thinkpad'
Module /usr/src/modules/thinkpad failed.
Perhaps /usr/src/modules/thinkpad does not understand --rootcmd?

Is there a package I forgot to install, or some step I didn't take 
prepping the sources?

Should I worry about the EXTRAVERSION variable in the kernel Makefile? 
It appears to be blank by default, but uname -a output looks like I 
should define it as "-1-686" to match the kernel-image-2.6.4-1-686 
package kernel.
