(TL;DR at the bottom)

I thought I was almost there. I didn't know so much about using git though, 
and already learned some more last night and morning.

All is copy and paste until "Step 8 - install QtMoko", git checkout v37_gta04.
I didn't have git in my qemu-image yet, so I installed git (and dialog), got 
.git-nonexistant-errors and initialized git:

apt-get install dialog
apt-get install git
git init

After that it didn't know anything about QtMoko yet, of course. I figured it 
should fetch information from somewhere else, and after some trial and error 
found on the front page of github:
root at qtmoko-buildhost:~# git remote add qtmoko 
https://github.com/radekp/qtmoko.git -f

It takes its time checking out some 250M of data (this step took most time 
waiting for a step to complete so far, apart from me figuring)

Then another remote for the kernel:
root at qtmoko-buildhost:~# git remote add radeklinux 
https://github.com/radekp/linux-2.6/ -f

and look for a recent kernel:
git checkout v3.2-gta04-qtmoko-v38

Now I got stuk. 
* Create package in buildhost:
cd linux-2.6

I am in /root of the buildhost. I think the checkout happened to that 
directory instead of linux-3.2...:
root at qtmoko-buildhost:~# pwd 
root at qtmoko-buildhost:~# ls
COPYING        Kbuild       Makefile        arch    debian    fs       ipc

Documentation  MAINTAINERS  REPORTING-BUGS  crypto  firmware  init     lib     
qtopiacore  security  tools
root at qtmoko-buildhost:~# 

I installed dpkg-cross, so I could run dpkg-buildpackage on something in 
root at qtmoko-buildhost:~# apt-get install dpkg-cross
root at qtmoko-buildhost:~# dpkg-buildpackage
dpkg-checkbuilddeps: Unmet build dependencies: debhelper (>= 7) quilt (>= 
0.40) uboot-mkimage
root at qtmoko-buildhost:~# apt-get install debhelper quilt uboot-mkimage

The dpkg-buildpkg exits with an error:

  Generating include/generated/mach-types.h

Is that "expected" with the current status of Linux v3.2-gta04-qtmoko-v38 ? 
Should I submit a bug report according to readme.bugs?

Besides that, it says (way at the start):
* Remove /etc/network/run and do make dir /etc/network/run
  Otherwise fstab mounting will fail for this directory
rm /media/card/etc/network/run
mkdir /media/card/etc/network/run

I probably don't write anything unknown here (and have no other solution 
anyway), but it's not a directory initially, but a link: 
root at qtmoko-buildhost:/media/card/dev# ls -latrh /media/card/etc/network/
lrwxrwxrwx  1 root root   16 Jan 27 22:39 run -> /dev/shm/network

Once I'm through, is it helpful if I give a try to expanding the guide with my 
findings, or should it not be necessary to get those dependencies in the first 

* I got an error compiling a (development snapshot?) kernel 3.2 for GTA04, 
should I submit a bug report or not? Is it something that is not supposed to 
happen, given the current state of that branch?
* the guide is mostly copy/paste, is it helpful if I expand it with apt-get 
for missing dependencies in my buildhost-image?

Thanks for the effort in the buildhost and the guide!
