Errors Installing GHCJS for use in StackOverflow question

Distribution quality warnings:
The 'description' field should be longer than the 'synopsis' field. It's
useful to provide an informative 'description' to allow Haskell programmers
who have never heard about your package to understand the purpose of your
package. The 'description' field content is typically shown by tooling (e.g.
'cabal info', Haddock, Hackage) below the 'synopsis' which serves as a
headline. Please refer to
<https://www.haskell.org/cabal/users-guide/developing-packages.html#package-properties>
for more details.

Distribution quality warnings:
'ghc-options: -O0' is not needed. Use the --disable-optimization configure
flag.
'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit
and not just imposing longer compile times on your users.
