Using Pacifist to uninstall a program (MacOS/Tiger)

New versions of Safari crash immediately for me, so I stick with 3.2.1 (Tiger). I can't update iTunes, either, because newer versions of iTunes require a newer version of Safari (for the iTunes store).

If I want to install an old version of Safari, Mac won't let me because there's already a newer version, but how to get rid of that?

Solution: Remove with Pacifist (e.g. Pacifist_2.6.dmg)

Directions:
Mount Safari 3.2.1 dmg package,
Run Pacifist.app,
Open Safari 3.2.1 package,
Select the lot,
Click install,
(Choose "Replace" when asked about the other version)
