Okay, I was able to get the _Haskell Platform_ approach to work, by doing the following: - Uninstall Haskell Platform. - Reinstall Haskell Platform, overriding the default suggested installation path with something _not containing spaces_. - Change my `~\AppData\Roaming\cabal\config` file from this: ``` extra-prog-path: C:\HaskellPlatform\8.6.5\msys\usr\bin, C:\Users\capnf\AppData\Roaming\cabal\bin ``` to this: ``` extra-prog-path: C:\HaskellPlatform\8.6.5\msys\usr\bin extra-prog-path: C:\Users\capnf\AppData\Roaming\cabal\bin ``` -db
