haskell-devscripts depends on hscolour, while hscolour build-depends on
haskell-devscripts. with force-depends installed haskell-devscripts,
hscolour builds fine. So it appears not all funtionality of haskell-devscripts
depends on hscolour.

This could be solved by

1) making hscolour not build-depend on haskell-devscripts.
2) splitting haskell-devscripts to two packages, one with the hscolour using
scripts, one with rest scripts.

Hi Riku,

we are considering to add hscolour as a Build-Dependency to ghc even...

The current setup works fine for everyone but those bootstrapping a new
architecture. For those few, I find it reasonable to expect them to do
what you did, e.g. force-install haskell-devscripts (or ghc, once it
build-depends on hscolour). Things would be easier if aba’s proposal
about Build-Depenes-Stage1 or however it will be called will be
implemented.

Where would you, as a porter, first look for information about breaking
such cycles? README.source?
