Newer Cabal doesn't actually break hs-plugins, the problem is mixing an older
version of Cabal linked against GHC's API and a newer version of Cabal.  This
is the same version mismatch issue that has become rather common with
ByteString.  To fix the build on my system, I simply replaced "Cabal >= 1.2.3"
with "Cabal == 1.2.3.0".
