We just merged a PR related to this; try again from the newest git?

Came a little bit longer with the newest git. But stopped with another module it couldn't find. Think it's me, need to dig into this a little bit. Thanks!

Solved
The versions I have (ghc 8.6.5 and cabal 3.0.0.0) does not play nice together. I had to use the v1-versions of configure and install. (v2- is default in cabal 3.0.0.0).
The makefile works fine for creating the binaries as it is, but when starting ghci there was things missing in the environment file. Here's the issue haskell/cabal#5559
