[Pkg-haskell-maintainers] Bug#658660: haskell-hastache: FTBFS - missing dependency on utf8-string

[Aaron M. Ucko]

Source: haskell-hastache
Version: 0.2.4-1
Severity: serious
Justification: fails to build from source

Builds of haskell-hastache in minimal environments (as on the
autobuilders) have been failing with the error

  hlibrary.setup: At least the following dependencies are missing:
  utf8-string -any

Could you please add build dependencies on libghc-utf8-string-* and
check with pbuilder or the like that no others are missing?

Thanks!
