Problems with make a new kernel

[Stefan Klose <klose%ibklose.de@localhost>]

Hello,

i want to make a new kernel with make depend and make.
The compiler breaks off with this errormessage;

../../../../lib/libkern/../../../../lib/libkern/Makefile.inc line 93:  
could not find ../../../../lib/libkern/../../../common/lib/libc/ 
Makefile.inc

I'm confused, it's not my first try to make a new kernel but this  
message I see at the first.

Where is the error???

Thanks

Stefan
