Hi!
There’s «Additional Packages» section [0] which lists packages that need to be installed in order to run full testsuite. But I couldn’t install dph-* ones, first errors I was getting were regular cabal-constraint ones. I wrote an author Ben Lippmeier, but he replied that dph-* packages were obsolete and not maintained anymore. I grepped and saw that all tests are under testsuite/dph folder. So: does GHC still run them at all? Should we edit wiki? Or edit test-suite?
Thanks!
