MacOS install issue with ncurses (locally fixed but maybe not ideally)

Error: ncurses directory not found at /usr/local/opt/ncurses
Install with: brew install ncurses
make: *** [release] Error 1

Self descriptive.

My fix:

❯ git diff                                                                                                          (base)

Maybe not ideal but it works. I think that type of checking is specific to how brew handles env vars within a particular recipe (that is HOMEBREW_PREFIX because on my system which is a M1 Mac mini there is no such thing as HOMEBREW_PREFIX on my env. I investigated the brew docs and it came up only in specification of writing a recipe but not a particular global, so it might function as some closure over the recipe and exporting then unexporting a ENV var during that 'install session.' I am just speculating though.

❯ echo $HOMEBREW_PREFIX                                                                                             (base)

I can submit a PR if this is good enough or let me know.
