So much googling to get mcrypt to work with 7.2...

brew install mcrypt
pecl install -f mcrypt

Confirmed with...
php -m

Ahh weird... I updated this to do a different method that I found. You can get libmcrypt installed via brew.

Hey Brant, this is helpful! I will link to it in the updated checklist.

you've got curly quotes instead of straight double quotes on lines

I fixed it in my fork, but it's probably just as easy to fix it here.

Also I got an error on line 36, and it looks like they changed it at https://getcomposer.org/download/

Should be
php -r "if (hash_file('sha384', 'composer-setup.php') === 'a5c698ffe4b8e849a443b120cd5ba38043260d5c4023dbf93e1558871f1f07f58274fc6f4c93bcfd858c6bd0775cd8d1') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
