can't install 64-bit haskell platform for mac os x

[Jesse Alama]

Hello,

I just tried to install the 64-bit haskell platform for Mac OS X 10.6.8. 
  I got the platform from

 
http://lambda.galois.com/hp-tmp/2011.2.0.1/Haskell%20Platform%202011.2.0.1-x86_64.pkg

The installation proceeds almost to the end; the installer writes its 
files, but then dies at the end saying:

   "The installation failed.

    The Installer encountered an error that caused the installation to 
fail.  Contact the software manufacturer for assistance."

Here is the installer log file:

If it helps, I have already successfully installed an installation of 
the 32-bit Haskell Platform installed; I'm trying to use the 64-bit 
version.  The installation error is repeatable (the installer tells me 
that installation might succeed if I simply try again).
