one package (at least) you use - probably graphviz - was compiled with a
version of `text` that is not the newest you have installed.
GHC selects the newest installed version of a package by default, cabal and
cabal-dev select the version that the other used packages require.
Add a -package text-0.11.2.0 flag to the command line.
