Hello again

I built the kernel from source (apt-src) from another machine, and 
created the new flavour xen as well. Now i have this:

DEB_BUILD_OPTIONS=parallel=8 AUTOBUILD=1 debian/rules binary-xen (i only 
wanted to build the flavour xen, which is derived from the serve flavour)

...
II: Done
install -d /root/linux-2.6.31/debian.master/abi/2.6.31-19.56/amd64
find /root/linux-2.6.31/debian/build/build-xen/ -name \*.ko | \
         sed -e 's/.*\/\([^\/]*\)\.ko/\1/' | sort > 
/root/linux-2.6.31/debian.master/abi/2.6.31-19.56/amd64/xen.modules

What is wrong here (i don't use git, because i want to do a local 
compilation), i couldn't find anything in the document you posted?
Furthermore i haven't done an ABI bump, as the ABI checks completes 
without an error.
