You don't have permission to install it in a way that all users of that
GHC will then be able to use it.  You should pass --user to "runghc
Setup install" for your desired effect.  (whereas I shouldn't because my
GHC itself is also compiled by my user and in my home directory - which
confused me once upon a time)
