Compile errors in recent rasa release(s)

I noticed that recent rasa versions run into compile failures, see e.g. http://104.239.175.197:8080/package/rasa

Configuring component lib from rasa-0.1.11...
Preprocessing library rasa-0.1.11...

src/Rasa/Internal/Buffer.hs:82:36: error:
    • No instance for (Show Eve.Internal.States.StateWrapper)
        arising from a use of ‘show’
    • In the first argument of ‘(<$>)’, namely ‘show’
      In the second argument of ‘($)’, namely
        ‘show <$> b ^. states . to M.toList’
      In the expression:
        intercalate "\n" $ show <$> b ^. states . to M.toList

The following error is simply because older GHC versions' lexer have problems when a line starts (without any preceding whitespace) with the #-} end marker.

src/Rasa/Internal/ActionMonads.hs:5:5:
    Cannot parse LANGUAGE pragma
    Expecting comma-separated list of language options,
    each starting with a capital letter
      E.g. {-# LANGUAGE TemplateHaskell, GADTs #-}
