loop-aes + kernel 2.6 - error building modules_image

[Michael Vert <vmike@gmx.net>]

Has anyone succeeded in creating a

  make-kpkg ... modules_image

with loop-aes in the "modules" tree?

Kernel sources 2.6.6, and the current loop-aes have been installed from 
the unstable distribution and are stored in /usr/src/linux and 
/usr/src/modules/loop-aes, resp..

(As required, the loop block devices has been removed from the kernel.)

The kernel itself builds fine (make-kpkg kernel_image), but the 
"modules_image" does not compile.

The error messages suggest that the source tries to include header files

  #include <linux/...>

but does not find them. These header are located at 
"/usr/src/linux/include/linux". But it seems that the Makefile does not 
generate a search path pointing to that directory.

Any hints or pointers?
