apt-get wierdness: when 6 is equal to 9

[Peter Jay Salzman <p@dirac.org>]

hello all,

problem: two systems with the same sources.list don't know about the same
  available packages.

explanation: i just built a new system, and scp'd over the sources.list file
  from an older machine.  both machines have the same /etc/apt/sources.list:


deb     ftp://ftp.us.debian.org/debian/ woody main non-free contrib
deb-src ftp://ftp.us.debian.org/debian/ woody main non-free contrib
deb     ftp://non-us.debian.org/debian-non-US woody/non-US main contrib non-free
deb-src ftp://non-us.debian.org/debian-non-US woody/non-US main contrib non-free

# Security
deb     http://security.debian.org/debian-non-US woody/non-US main
deb-src http://security.debian.org/debian-non-US woody/non-US main
deb     http://security.debian.org/debian-non-US woody/non-US contrib
deb-src http://security.debian.org/debian-non-US woody/non-US contrib

# Wine     apt-get -b source wine
#deb     http://gluck.debian.org/~andreas/debian wine main
#deb-src http://gluck.debian.org/~andreas/debian wine main

yet, on the older machine:

  satan# dpkg -l "*mesa*"
  pn  giram-gnome-me <none>   (no description available)
  pn  giram-mesa     <none>   (no description available)
  un  mesa-dev       <none>   (no description available)
  ii  mesademos      3.4.2-1  Example programs for Mesa (and OpenGL in gen
  rn  mesag-dev      <none>   (no description available)
  pn  mesag-glide2-d <none>   (no description available)
  pn  mesag-widgets- <none>   (no description available)
  pn  mesag3         <none>   (no description available)
  pn  mesag3+ggi     <none>   (no description available)

  un  mesag3-glide   <none>   (no description available)
  pn  mesag3-glide2  <none>   (no description available)
  pn  mesag3-widgets <none>   (no description available)
  ii  xlibmesa-dev   4.1.0-5  XFree86 version of Mesa 3D graphics library 
  ii  xlibmesa3      4.1.0-5  XFree86 version of Mesa 3D graphics library
  ii  xlibosmesa-dev 4.1.0-5  Mesa/XFree86 offscreen rendering library dev
  ii  xlibosmesa3    4.1.0-5  Mesa/XFree86 offscreen rendering library

and on the newer machine:

  # dpkg -l "*mesa*"
  un  mesa-dev       <none>   (no description available)
  ii  mesademos      3.4.2-1  Example programs for Mesa (and OpenGL in gen
  ii  mesag-dev      3.1-17   Development library for Mesa [libc6].
  pn  mesag-glide2-d <none>   (no description available)
  pn  mesag-widgets- <none>   (no description available)
  ii  mesag3         3.1-17   A 3-D graphics library which uses the OpenGL
  pn  mesag3+ggi     <none>   (no description available)
  pn  mesag3+ggi-dev <none>   (no description available)
  un  mesag3-glide   <none>   (no description available)
  pn  mesag3-glide2  <none>   (no description available)
  pn  mesag3-widgets <none>   (no description available)

i've typed apt-get clean && apt-get update a bunch of times, yet the newer
machine doesn't seem to know about the xlibmesa* packages.

how can two machines with the exact same sources.list file not know about the
same packages?
