[Pkg-haskell-maintainers] Bug#737689: haskell-diagrams-core: inadequately versioned build-depends on

[peter green]

Package: haskell-diagrams-core
Version: 0.7.0.1-1

I run a debian derviative called raspbian which rebuilds debian armhf 
for the raspberry pi (and potentially other armv6 hardware but the Pi is 
the only armv6 hardware anyone seems to care about).

Recently a new version of haskell-diagrams-core landed in debian-jessie 
and was pulled into raspbian jessie. One of our autobuilders then tried 
and failed to build it. Looking at the build log it appears that the 
build-dependency on libghc-monoid-extras-dev was inadequately versioned.
