Building stack with ghc-8.4.x requires a whole lot of version overrides -- most
notably Cabal 2.4.x --, so we don't bother and just use the one built with the
latest compiler instead.
Why is qtmultimedia only needed on Darwin? Why does it only fix 5.9, not
5.11? These things I do not know. What I do know is that, for some
reason, this makes qt59.qtwebkit build on Darwin.
I think the reason it hasn't also fixed 5.11 might be something to do
with the version of qtmultimedia, but I don't know enough about Qt or
cmake to figure it out. The error when trying to build qt511.qtwebkit
(with or without these changes) is:
CMake Error at Source/cmake/OptionsQt.cmake:739 (find_package):
Could not find a package configuration file provided by "Qt5Multimedia"
(requested version 5.2.0) with any of the following names:
Qt5MultimediaConfig.cmake
qt5multimedia-config.cmake
Add the installation prefix of "Qt5Multimedia" to CMAKE_PREFIX_PATH or set
"Qt5Multimedia_DIR" to a directory containing one of the above files. If
"Qt5Multimedia" provides a separate development package or SDK, be sure it
has been installed.

when calling python3Packages.gpgme, it was still picking python2.
Changed withPython into pythonSupport since it's the convention.
I had to enable ncurses too because of this error when configuring:
