app-text/pandoc-1.9.4.2: Could not find module `Data.Default'

[CasperVector]

The problem is in app-text/pandoc/files/pandoc-1.9.4.2-ghc76.patch, since it introduced Data.Default into Setup.hs: GHC 7.4.2 (the version on my machine) does not provide builtin Data.Default, while dev-haskell/data-default is not set as a dependency in the ebuild.

See below for the build.log.
