Nope:

  $ sudo apt-get dist-upgrade

  The following packages have been kept back:
    dpkg-dev fakeroot g++ g++-4.1 libc6-dev libstdc++6-4.1-dev
  0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.

Nope:

  $ sudo apt-get install dpkg-dev fakeroot g++ g++-4.1 libc6-dev libstdc++6-4.1-dev

  Some packages could not be installed. This may mean that you have
  requested an impossible situation or if you are using the unstable
  distribution that some required packages have not yet been created
  or been moved out of Incoming.
  The following information may help to resolve the situation:

  The following packages have unmet dependencies:
    dpkg-dev: Depends: dpkg (>= 1.14.0) but 1.13.24ubuntu6 is to be installed
    fakeroot: Depends: libc6 (>= 2.5-5) but 2.5-0ubuntu14 is to be installed
    g++: Depends: cpp (>= 4:4.1.2-2ubuntu6) but 4:4.1.2-1ubuntu1 is to be installed
         Depends: gcc (>= 4:4.1.2-2ubuntu6) but 4:4.1.2-1ubuntu1 is to be installed
    g++-4.1: Depends: gcc-4.1-base (= 4.1.2-15ubuntu2) but 4.1.2-0ubuntu4 is to be installed
             Depends: gcc-4.1 (= 4.1.2-15ubuntu2) but 4.1.2-0ubuntu4 is to be installed
             Depends: libc6 (>= 2.6-1) but 2.5-0ubuntu14 is to be installed
    libc6-dev: Depends: libc6 (= 2.6.1-0ubuntu1) but 2.5-0ubuntu14 is to be installed
    libstdc++6-4.1-dev: Depends: gcc-4.1-base (= 4.1.2-15ubuntu2) but 4.1.2-0ubuntu4 is to be installed
                        Depends: libstdc++6 (>= 4.1.2-15ubuntu2) but 4.1.2-0ubuntu4 is to be installed
  E: Broken packages


Furthermore, I'm not too surprised, since if it were that easy,
"apt-get upgrade" should handle it for me automatically.
