It makes sense to me that this could be the source of the trouble.  I'd 
like to uninstall the 32-bit version and install the 64-bit version. 
According to

   http://www.haskell.org/haskellwiki/Mac_OS_X

the way to uninstall the haskell platform is to call

   /Library/Frameworks/GHC.framework/Tools/Uninstaller

but in my case the Tools subdirectory of GHC.framework somehow doesn't 
exist.  How can I manually trash the 32-bit installation?

Thanks,

Jesse
