I suggest to pay more attention to haskell's standard library.

"allButLast" is called "init" in Data.List module.

Second, do not use explicit recursion. You can capture recursion using some high-order function like map, filter, foldr and so on:

lastToTheLength xs = map f xs where f = const . last $ xs

And just to play a little Haskell golf: lastToTheLength = ap (flip map) (const . last) -- Live well, ~wren
