[Pkg-haskell-maintainers] Bug#719258: haskell-th-extras: FTBFS: Could not find module `Data.Generics'

[Aaron M. Ucko]

Source: haskell-th-extras
Version: 0.0.0.2-1
Severity: serious
Justification: fails to build from source

Builds of haskell-th-extras in minimal environments (as on the
autobuilders) have been failing:

  src/Language/Haskell/TH/Extras.hs:5:8:
      Could not find module `Data.Generics'

Could you please declare build dependencies on libghc-syb-* and
confirm with pbuilder or the like that you haven't missed anything
else?

Thanks!
