When you run "runhaskell Setup.lhs configure" cabal will try to  
install it globally. I am guessing that your two libraries are  
installed as a user (which is the default for cabal-install): run  
"ghc-pkg list" and check if binary and bzlib are under the user  
section. Cabal will not let you install global packages that depend  
on user-local packages, and that's for a good reason. It is however  
rather confusing.

You can either tack on "--global" when you run cabal-install if you  
want bzlib and binary installed globally, or you can tack on "--user"  
when you "runhaskell Setup.lhs configure" for the timber compiler.
