Hummm.  Well, I confess that I'm confused.  Cabal 1.1.4 should work, because 
that's what I have on my machines; I've just tested it here.  The only thing 
I can think of is that the 'runhaskell' command is still bound to your old 
GHC, or to something else (Hugs maybe?).  If that's the case, you can edit 
the makefile and set the 'RUNHS' variable in the first line to the full path 
to your 6.5 runghc.  Or you can edit the .cabal files as suggested above.
