"link group ps2pdf is broken"

[Noel J. Bergman]

Upon any upgrades of Ghostscript (Karmic upgraded from Jaunty):

  Setting up ghostscript (8.70.dfsg.1-0ubuntu1) ...
  update-alternatives: using /usr/bin/ps2pdf14 to provide /usr/bin/ps2pdf (ps2pdf) in auto mode.
  update-alternatives: warning: not replacing /usr/bin/ps2pdf with a link.
  update-alternatives: warning: forcing reinstallation of alternative /usr/bin/ps2pdf14 because link group ps2pdf is broken.

Checking /usr/bin/ps2*:
  $ ls -ld /usr/bin/ps2*
  -rwxr-xr-x 1 root root 786 2009-08-01 12:49 /usr/bin/ps2ascii
  -rwxr-xr-x 1 root root 2822 2009-08-01 12:49 /usr/bin/ps2epsi

  lrwxrwxrwx 1 root root 8 2009-08-02 08:33 /usr/bin/ps2txt -> ps2ascii

Notice that ps2pdf is not a symlink. Instead it contains:

  #!/bin/sh
  # $Id: ps2pdf 8107 2007-07-05 19:04:29Z till $
  # Convert PostScript to PDF.

  # Currently, we produce PDF 1.4 by default, but this is not guaranteed
  # not to change in the future.
  version=14

  ps2pdf="`dirname $0`/ps2pdf$version"
  if test ! -x "$ps2pdf"; then
   ps2pdf="ps2pdf$version"
  fi
  exec "$ps2pdf" "$@"

Checking /etc/alternatives:

  $ ls -l /etc/alternatives/ps2pdf
  lrwxrwxrwx 1 root root 17 2009-08-02 08:33 /etc/alternatives/ps2pdf -> /usr/bin/ps2pdf14

The alternatives setup and the current shell script are effectively the same, but we should decide which approach we want to talk, and execute it. Either remove /usr/bin/ps2pdf and replace it with a symlink to /etc/alternatives/ps2pdf or remove the link setup so that the install doesn't complain.
