Comment(by KrzysztofSkrzetnicki):

 Replying to [comment:1 juhp]:
 > Maybe {{{runghc configure --ghc-opt=-dynamic}}} is a workaround?

 It might work, but not when TH is used. For example it fails for me:

 $ cabal install --ghc-option=-dynamic

     Dynamic linking required, but this is a non-standard build (eg. prof).
     You need to build the program twice: once the normal way, and then
     in the desired way using -osuf to set the object file suffix.
 cabal: Error: some packages failed to install:
 slayer-0.3.1 failed during the building phase. The exception was:
 ExitFailure 1

 I have no idea if the patch specified above is going to work or not.
