I've followed the instructions in debian/README.source.  There were a
couple of things I had to infer - possibly wrongly - and the last step
in the recommended workflow doesn't get very far at all for me - so I'd
appreciate if you could review the following.

First, I guessed that all the example workflow steps should be run in
the root of the QtMoko tree.  Is that right?

Second, I found that the pdebuild-cross-create step created an armel
chroot.  I then copied debian/pdebuild-cross/pdebuild-cross.rc to
/etc/pdebuild-cross/ and debian/pdebuild-cross/multistrap-* to
/etc/multistrap/ and reran the pdebuild-cross-create step, and it looked
better:

  ...

  Multistrap system installed successfully in /var/lib/pdebuild-cross/build/.

  Compressing multistrap system in '/var/lib/pdebuild-cross/build/' to a tarball called: 'pdebuild-cross-armhf-wheezy-4.7.tar.gz'.

  Removing build directory: '/var/lib/pdebuild-cross/build/'

  Multistrap system packaged successfully as '/var/lib/pdebuild-cross/pdebuild-cross-armhf-wheezy-4.7.tar.gz'.

Was installing those configs the right thing to do?

Next the fix-pdebuild-cross step, which looked fine apart from these
warnings:

  ...
  W: /root/.pbuilderrc does not exist
  ...
  dpkg-architecture: warning: specified GNU system type arm-linux-gnueabihf does not match gcc system type i486-linux-gnu, try setting a correct CC environment variable
  ...

Do those indicate that I missed something?

Next the QtMoko build step as per README.source:

  neil at neil-laptop:~/qtv46/qtmoko$ CROSSARCH=armhf CROSSVERS=4.7 DIST=sid QTMOKO_DEVICES=gta04 pdebuild-cross
  Need to create a new pbuilder crossbuilding chroot first.
  Use pdebuild-cross-create to create one.

I guessed that the 'sid' here might be a typo, and so tried 'wheezy'
instead, but it still didn't get very far:

Do you know what is going wrong here?  I can provide the complete
transcript if it's needed.

Many thanks,
