Cabal-1.4: library-dirs and include-dirs missing from package description after install

[Alistair Bayley]

I'm trying to build and install Takusen 0.8.2 with a new .cabal and
Setup, using Cabal-1.4.0.0. The Setup program writes out an updated
Takusen.buildinfo (below) from the postConf hook. However, the
library-dirs and include-dirs fields are not included in the package
description when installed.

Any ideas as to what I'm doing wrong?
