MacOS fails to install

Created by: mouse07410

Describe the bug bootstrap-haskell fails on MacOS Mojave 10.14.3 (Macports present).

Here's the complete log: ghcup-failed.txt It appears to be failing on

cabal new-install --symlink-bindir=/Users/ur20980/.cabal/bin --jobs=1 cabal-install

Here's "condensed" log: new-update2.log.txt

It shows the actual error - failure to compile Network/TCP.hs because

Network/TCP.hs:41:6: error:
    Module ‘Network.Socket’ does not export ‘sClose’
   |
41 |    , sClose, setSocketOption, getPeerName
   |      ^^^^^^

To Reproduce

1. Clear the previous (the "real") Haskell Platform installation by removing everything Haskell-related.
2. Clone this repo.
3. Set PATH to $HOME/.cabal/bin:$HOME/.ghcup/bin:$PATH
4. cd ghcup; ./bootstrap-haskell
5. Observe the result.
