* cmdline/apt-get.cc:

  - do two passes when installing tasks, first ignoring dependencies,
    then resolving them and run the problemResolver at the end
    so that it can correct any missing dependencies. This should
    fix livecd building for kubuntu (thanks to Jonathan Riddell 
    for reporting the problem)
