[zimoun]

Hi,

Thanks for he report.

It is 2 different issues; therefore I propose to keep them separated.

This one is about the importer.  I think it comes from the current
cabal.scm parser; not able to deal with:

--8<---------------cut here---------------start------------->8---
-- We need to test and benchmark these modules,
-- but do not want to expose them to end users
library attoparsec-internal
  hs-source-dirs: internal
  build-depends: array,

[...]

library
  build-depends: array,
[...]
                 attoparsec-internal
--8<---------------cut here---------------end--------------->8---

Could you open another bug report for that?



Let focus on this one…

…for this bug report.  Hum, I do not know how where the error comes
from.
