This belongs to a SuperCollider wrapper:
 http://www.slavepianos.org/rd/f/409875/

You don't need to install that wrapper, if you do not want to use
SuperCollider. In this case remove the Hsc dependency and the
SuperCollider modules from Haskore.cabal.
 I would like to tell Cabal which modules are required and which are
supported, or recommended, but not needed. I could split Haskore into
several packages, but then again, installation of Haskore and its
sub-packages becomes uncomfortable and the Haddock documentation has no
longer a common table of contents. I tried to write custom Setup code for
finding out which parts of Haskore cannot be installed due to unsatisfied
dependencies, but this is more complicated than I hoped.
