It's a bug in the package that was exposed when Cabal-1.6.0.2 started
checking for header files and C libs. I reported the bug to the package
maintainer at the time of the release of Cabal-1.6.0.2.

Until the maintainer updates it, the fix is to edit the .cabal file and
simply remove the mention of Linker.h. You can use the new cabal unpack
command:

  cabal unpack plugins
  cd plugins-1.4.0
  vi plugins.cabal
  cabal install
