I'm having the same problem on 10.3.9. I *seriously* doubt this is a problem with anyone's 10.3 install, because I downloaded a number of releases all the way back to 0.2.0.31 which finally contained an installer package that would work. I downloaded and tried both the "vidalia bundles" and the "expert bundles" that only contained Tor -- The results were the same for both types of installation bundles.
Not being a lazy user who just whines "fix it!", I started comparing the install images that work with those that do not. I found that the invisible ".contained_packages" folder contained packages that had significant internal differences: In the packages in the releases that wouldn't install, most of the <installer-package-name-here>.pkg/Contents/ Resources/ folders were missing the copies of (and/or aliases to) the "Archive.bom" and "Archive.pax.gz" files as well as the "<installer- package-name-here>.sizes" and "<installer-package-name-here>.info" files. I made a read/write copy of the image of the problem release and tried patching up the packages by hand, but all I managed to get was a different error message: "Missing or old Bill Of Materials." I hope this helps you track down the problem with these installers. Joel
