Okay, I got it.  I suspect the problem is some kind of misconfiguration 
on our part, but here's how to fix it:

In the directory "/Library/Receipts", delete the following 
subdirectories:
MzScheme.pkg
PLT.pkg
MrEd Framework.pkg
MzScheme Framework.pkg


This should solve your problem.  Thanks for your patience, and let us 
know if there are any further issues.
