Thanks, that helped.

What I should have mentioned is that I am sandboxing my GHC installations, so whenever I compile 
HEAD I can switch to a different sandbox and install the new compiler within that sandbox. Now I 
can just install packages into user database without worrying that my original database gets 
cluttered with duplicate libraries. I managed to install some of the packages using plan B. This 
is tedious (I'd rather have dependencies resolved, downloaded and installed automatically by 
cabal) but works as long as packages from hackage are compatible with HEAD. Unfortunately some of 
them are not, which prevents me from installing libraries that I need (like blaze-builder) but I 
guess that can't be helped.
