Comment (by mpickering):

 Since Herbert merged the commit which made Semigroup a superclass of
 Monoid it became much more difficult to build packages with HEAD.
 https://phabricator.haskell.org/rGHC8ae263ceb3566a7c82336400b09cb8f381217405

 The most reliable way I found now was to use the package overlay he posted
 about but it is more fiddly to set up.
