  Binary package hint: transcode

  Hi,

  using the logoaway filter in transcode produces the following error:

  [transcode] warning: Unable to load filter logoaway:
  /usr/lib/transcode/filter_logoaway.so: undefined symbol:
  DestroyConstitute

  This is also known for other distribution (e.g. Debian) which I think
  is then an upstream problem. The problem with filter_logoway is that
  during the compilation there is no check of all used external
  funtions. A couple of months ago the API of imagemagick has changed
  and DestroyConstitute() was replaced by ConstituteComponentTerminus()
  .

  So, the solution is to change the in line 868 of
  filter/filter_logoaway.c

  DestroyConstitute(); <--> ConstituteComponentTerminus();

  I found this in the 10.04 development version, but as I said this
  error may exist also in older distributions as well.

  >lsb_release -rd
  Description:    Ubuntu lucid (development branch)
  Release:        10.04

  The hint in the change of the imagemagick API I found on launchpad as
  well:

  Maybe it is worth to check other packages in lucid as well before the
  final release!
