I had the situation where I had removed my kernel source tree, and there 
was a realtime-lsm-source update, which I wanted to build and install.

Since realtime-lsm requires a kernel rebuilt with

CONFIG_SECURITY_CAPABILITIES=m

It is reasonable to assume that the person building realtime-lsm will 
have the linux-source-* package installed if not unpacked.

Also, since make-kpkg package can be used to build both the realtime-lsm 
module and the custom kernel required by realtime-lsm, make-kpkg is a 
more logical choice for building the realtime-lsm module than 
module-assistant. I found myself frustrated trying to use 
module-assistant to build the realtime-lsm module. The directions for 
using make-kpkg in /usr/share/doc/alsa-source also helped me build the 
realtime-lsm module, but the directions in /usr/src/realtime-lsm-source 
simply state:

[quote]

In order to build the realtime kernel module from source use
module-assistant.

e.g.

module-assistant update
modula-assistant build realtime-lsm

You need to have the kernel header files installed for this to work.

[end quote]

Why have kernel-headers-[insert-version-number] installed if one needs 
the full kernel source to build a kernel with
Since realtime-lsm requires a kernel rebuilt with 
CONFIG_SECURITY_CAPABILITIES=m anyway?

Unpacking the kernel source and realtime-lsm source, creating a symbolic 
link /usr/src/linux pointing to /usr/src/linux-source-2.6.17 then 
copying the current kernel configuration from /boot to 
/usr/src/linux/.config didn't allow:

make-kpkg modules-image

to succeed (as shown in the quoted errors above).

What was needed after:

cp /boot/config-2.6.17 /usr/src/linux/.config

was:

cd /usr/src/linux
make modules_prepare

before:

make-kpkg modules-image

After that I could do:

cd /usr/src
dpkg -i realtime-lsm-module*.deb

Problem solved!
