Using a compatibility layer is not that easy at the moment. There is a
feature which will likely go into some upcoming version of Cabal that
will make it easier to depend on different packages (eg a
compat-finitemap) depending on what packages versions we are building
against. For example you'd put something like the following in
the .cabal file:

configuration: package(base >= 2.0)
build-depends: compat-finitemap

However since this feature is not available yet it's rather hard to add
a compatibility layer. Generating the .cabal file is a no-no.
