Comment 2 for bug 558461

/usr/bin/buildd has been renamed in ubuntu-dev-tools 0.84:
  * Rename buildd to ubuntu-build to resolve filename conflict
    (Closes: #558816).

To make upgrades work correctly buildd needs to declare Replaces and Breaks on ubuntu-dev-tools (<= 0.83).
I prepared the changes for the package in maverick in merge bug #580724.

Once the package has been uploaded to maverick it should be fixed in lucid:

sbuild (0.59.0-1ubuntu2.1) lucid-proposed; urgency=low

  * buildd: Declare Replaces and Breaks on ubuntu-dev-tools (<= 0.83) as
    both packages contain /usr/bin/buildd. (LP: #558461)
