Probably a duplicate of #155, which adds support for stack. Except it seems your symptoms are different?

If I understand this correctly, every time the user modifies ~/.hawk/prelude.hs hawk will invoke ghc via System.Process.readProcessWithExitCode "ghc" to (re-)compile the user prelude. However, stack does not install a particular ghc in the $PATH. Of course, running stack exec hawk in the source base will compile successfully the prelude and one can use hawk thereafter. This or simply adding the stack installed ghc path to $PATH would be temporary ways around this issue, albeit a tad cumbersome.
