Application Installer broken


Hi all,
I've recently experienced a rash of crashes with the native osx application installer (you know, to open .pkg files... ) The crashes almost regularly now, and there are files that I have not been able to intsall because the Installer crashes every time I open it. I've tried re-installing the installer from the Tiger DVD, but you can't really "install" it, you have to drag-and-drop copy, which isn't quite the same. The problem is compounded by the fact that a "pal" of mine deleted all of the pkgs from my /library/receipts folder "in order to save disc space" rendering me unable to run permissions checks and fixes. I know different people feel differenly about the validy of running permissions checks, but I'm kind of wondering now if that might have something to so with it. So... my 3 questions are...

1) anything I can do about the receipts/permissions issue short of re-installation?

2) any idea where I could get an installer .pkg (not that I could open it) so to re-install the (this is getting rediculous)

3) Are there any other apps out there I could use... anyone having the same problems?

I have double checked all of the pkgs I'm attempting to install and they're all kosher, so it's not a matter of invalid or bad pkgs.

As always, I humbly appreciate and accept all input.
THanks a bunch.
