I'm a little lost as to exactly what changes you want. Can you send a darcs patch against the base and syb repos please?: http://darcs.haskell.org/ghc-6.10/packages/base/ http://darcs.haskell.org/ghc-6.10/packages/syb/ Currently everything is in the syb package.

That's fine, but do I need to build the entire compiler to be able to compile the base package?

If you want to move the Data class then you'll definitely have to rebuild GHC, and to change the line gENERICS = mkSybModule (fsLit "Data.Generics.Basics") to gENERICS = mkBaseModule (fsLit "<wherever you put it>") in compiler/prelude/PrelNames.lhs

Currently if I try to `runhaskell setup.hs configure' on base I get `attempting to use module `Prelude' (Prelude.hs) which is not loaded'...

You can't compile programs (like Setup.hs) in a base tree, as it will try to use the modules from the base tree rather than those from the installed base package. Thanks Ian
