I can't find the uninstaller. I installed some service using a pkg file and now I want to get rid of it. How do I do that? I would prefer not to use lsbom and rm and stuff. It looks scary.
Not a direct answer to your question, but you can also use "Suspicious Package", a QuickLook plug-in for Finder, to see what files a package installed: http://www.mothersruin.com/software/SuspiciousPackage/
Depending on what files were installed where, you may be able to find them in Finder and drag to the trash; otherwise you may have to go into Terminal and rm around.
For the most part, Mac applications don't have uninstallers because they're rarely needed. You can almost always just toss the undesired offender into your trash.
