It seems to me that this is a more general problem affecting all of our
Haskell packages.  The configure phase that you didn=E2=80=99t paste should=
that modules are provided by slightly different packages.

The haskell-build-system suffers from non-determinism.  It might just be
limited to the package database files that are generated by ghc-pkg
(where readdir is used and the result isn=E2=80=99t sorted).

I=E2=80=99m opening a bug report for this issue.
