Solving the problem of pandoc and gitit binaries taking so much space,
would require splitting the packages in two. Right now haskell-pandoc and
haskell-gitit are packaged with binaries and modules inside, and the module
part depend on all the other packages, including GHC. If we split each of
them into two, say pandoc (binaries) and haskell-pandoc (modules), then you
could just install the binaries without having to depend on GHC.
