This is also a good time to add upper bounds to dependencies, in accordance 
with the package versioning policy:

http://haskell.org/haskellwiki/Package_versioning_policy

For instance, with accurate dependencies the above would become

flag splitBase
   description: Choose the new smaller, split-up base package.
library
   if flag(splitBase)
     build-depends: base >= 3.0 && < 3.1, containers >= 0.1 && < 0.2
   else
     build-depends: base >= 2.0 && < 3.0
