You can do "cabal unpack hxq" and update the file hxq.cabal; I tried it
and there are many more things that need updates. Your best bet would be
to ask the author to update the package. Otherwise, you could ask the
Haskell Café if someone would like to take over maintenance of HXQ.

Apparently someone did update HXQ : Leonidas Fegaras, the original maintainer, updated HXQ on the 7 january 2016. I can only assume that Stanislaw contacted him directly.

Just to conclude the discussion on a positive note !
