[Pkg-haskell-maintainers] Bug#645573: haskell-hipmunk: FTBFS: errors building documentation

[Aaron M. Ucko]

Source: haskell-hipmunk
Version: 5.2.0.4-1
Severity: serious
Justification: fails to build from source

Automatic builds of haskell-hipmunk's architecture-dependent packages
(which run without build-depends-indep) have been failing:

  [ ! -x /usr/bin/haddock ] || debian/hlibrary.setup haddock --builddir=dist-ghc --hyperlink-source
  Running Haddock for Hipmunk-5.2.0.4...
  Preprocessing library Hipmunk-5.2.0.4...
  Running hscolour for Hipmunk-5.2.0.4...
  Warning: The documentation for the following packages are not installed. No
  links will be generated to these packages: StateVar-1.0.0.0, array-0.3.0.2,
  base-4.3.1.0, rts-1.0, containers-0.4.0.0, ghc-prim-0.2.0.0,
  integer-gmp-0.2.0.3, transformers-0.2.2.0
  hlibrary.setup: dist-ghc/doc/html/Hipmunk/haddock-prolog23382.txt: invalid

  make: *** [build-haddock-stamp] Error 1

I'm not sure why they're trying to run haddock at all (though I will
note that haskell-devscripts's dependency on ghc-haddock makes the
command's conditional redundant), or why other packages with your
standard setup fare better, but there you have it; could you please
take a look?

Thanks!
