  * Require HsColour by default
  This should stop us ending up without HsColour'ed sources on some
  platforms.
  
  We also now tell Cabal where to find HsColour, rather than it finding
  it itself.

    M ./Makefile -1 +9
    M ./libraries/Makefile -2 +6
    M ./mk/config.mk.in +2
    M ./mk/validate-settings.mk +1
