Arch runs the new GHC 7.10 release.  When GHC went from 7.8 to 7.10
there were incompatible changes made to the base packages.  ghc-vis
has issues with the updated base packages, described in its bug report
list (with possible workarounds):

  https://github.com/def-/ghc-vis/issues/7

Your builds are failing when trying to build old versions
of glib and cairo (prior to their ghc 7.10 fixes).

It also seem graphviz has also not yet been updated:
