I'm guessing what happened is that during the install the build system decided 
to rebuild ghc-pkg (I'm not sure why), but by that time you had already 
installed the new compiler, and the previous interface files weren't compatible 
with the new compiler.  (I don't know why that would be the case either, since 
both compilers are 6.6...).

You might be able to work around it by

   $ (cd compat && make clean && make UseStage1=YES)
   $ (cd utils && make clean && make UseStage1=YES)
