#2690: Problem building HEAD when a newer version of Cabal is installed

        Type:  bug     |      Status:  new     
    Priority:  normal  |   Component:  Compiler
     Version:  6.11    |    Severity:  normal

Architecture:  x86     |          Os:  MacOS X 
-----------------------+----------------------------------------------------
 I get the following error when building HEAD.  I'm using the release
 candidate ghc-6.10.0.20081007 from the OS X installer as the bootstrapping
 compiler.

 This seems odd since the Cabal I have in my build tree is 1.5.5; version
 1.6.0.0 is installed for the bootstrapping compiler, but IIRC stage1 is
 supposed to be built using libraries/Cabal instead of the installed
 version.
