Makefile Issue

[Jkx]

Hy, all. This is my first post here. So let me introduce myself.
I 'm working in a high scool in France as a developper. We plan to 
use OpenMoko as an embedded test plate-form for students .. 

While, I'm searching for a way to build the devel-image, I
run into a issue. Here is the error:

=================================================================================
NOTE: package linux-2.6.20-r3: task do_unpack: started
NOTE: Unpacking /opt/moko/sources/linux-2.6.20.tar.bz2 to /opt/moko/build/tmp/work/fic-gta01-linux/linux-2.6.20-r3/

NOTE: Task failed:
NOTE: package linux-2.6.20-r3: task do_unpack: failed
==================================================================================

As you can see, the default kernel config file is missing .. what can I do to 
fix that ? 


Thanks for any help. Bye ;)
