Hi Andreas T.,

The upload of bioperl-run/1.7.1-2 claims to have solved this bug.
However, it is using a versioned Conflicts rather than "Breaks+Replaces"
(as policy requests and Andreas B. recommended).  This puts a higher
constraint on dpkg/apt and normally not needed for simple cases of files
moving between binary packages.

 * If the Conflicts is truly required in this case, then please
   document why (and the upload would /still/ need a Replaces).
 * Otherwise, please use "Breaks+Replaces" instead of Conflicts.

Thanks,
~Niels
