Haskell copr builds for F26 failing?

[Róman Joost]

Hi,

I'm wondering why all my package builds for F26 are failing with:

    + ghc --make -no-user-package-db -dynamic Setup
/usr/lib64/ghc-8.0.2/package.conf.d/package.cache: openBinaryFile: does not exist (No such
file or directory)

I'm trying to reproduce the problem locally where mock fails as well
with the same error. A 'dnf whatprovides' claims that the file should be
provided by the ghc-compiler package, so I wonder why it isn't present.

Logs:

Spec:

Project (builds):

    https://copr.fedorainfracloud.org/coprs/romanofski/gtfsschedule/builds/

Am I missing something simple? Many thanks for any pointers?

Kind Regards,
