Perhaps there is some problem with the external libraries. I have just succesfully tested the latest version in ubuntu, with liblapack-dev and libatlas-base-dev.

Thanks for looking. I agree it's probably my config. It's still causing me a problem but feel free to close the ticket.

@albertoruiz I'm a bit confused by your outputs, it says

/opt/ghc/8.2.1/lib/ghc-8.2.1/package.conf.d

but further down

GHCi, version 8.0.2

That's two different GHC versions.

Sorry, I run the test in a normal terminal, outside the docker container used for a clean install. I have tested again without problems.

Thanks for pointing this out.

Cannot now reproduce.
