Mmm, I see... well, is the .bom format completely specified anywhere?
Even if ditto can't extract anything, if I can write a tool that can
modify the permissions for me, then that will work.
This isn't as crazy as it sounds, there is a guy that is doing this via
a hexeditor already:

I would just like to do this properly, via a tool that knows the format.
Thanks,
Cem Karan

You can't. You are clinging to a forlorn hope.
The "packages" in the Receipts directories have the same names as
installer packages, but have been stripped of the Contents/
Archive.pax.gz files, which contain the files that were installed.
Archive.bom is still present, as a listing (or "receipt") of what was
installed, but a listing is not the same thing as the actual files
themselves. A .bom (bill-of-materials) file is _not_ an archive.
Find an installer .pkg package and examine the contents; then compare it
to the receipt of the same name. The very, very large Archive.pax.gz
file is absent. Otherwise, it would not be practical to keep the
receipt; imagine keeping the entire archive of every OS installation.
