[Haskell-cafe] "cabal sdist" oddity

[Sven Panne]

Cabal from HEAD started to issue the warning

   "Warning: Cannot run preprocessors. Run 'configure' command first."

when running "cabal sdist" after a "cabal install", see e.g.
https://travis-ci.org/haskell-opengl/OpenGL/jobs/74581138#L264. Previous
versions didn't do this, see e.g.
https://travis-ci.org/haskell-opengl/OpenGL/jobs/74581137#L264. Somehow the
warning doesn't make sense, because the package has obviously been built
before, so configuration must have happened, too.

Is this a new bug in Cabal?

Cheers,
   S.
