This seems to answer your question:

So it appears that all three of the packages that you ask about install fine, 
only cabal install itself doesn't. (I use the --user and --prefix=... flags 
on my "Setup configure"s.)

As the ghc-pkg list output quoted earlier reveals, after running the cabal 
install bootstrap script, I have several Cabal versions installed. At this 
point, I got creative and tried to compile the maybench Setup.lhs using ghc 
-v --make Setup.lhs. The output contained the encouraging line:

> hiding package Cabal-1.1.6.2 to avoid conflict with later version 
Cabal-1.4.0.2

and using this ghc-6.6.1-compiled Setup.lhs, I was able to complete the 
installation of maybench. One explanation of the earlier failure could be 
that runhaskell doesn't take --user packages into account.

In any case, there were the minor matters

but I was able to install those without additional problems. Also:

Nevertheless, it didn't. And, as you can see on the 
http://buildbot.darcs.net/buildbot-darcs/waterfall display, tn20 now runs 
maybench.

Thanks a lot and best regards
