Wiki Home may need updates; getting gyb for a Mac fails both ways

[kdraeder]

Maybe there are some precursor commands I need to know, but simply following the instructions doesn't work for me.

>> bash < ( curl -s -S -L https://git.io/gyb-install )
Missing name for redirect.

>> bash
>> curl -s -S -L https://git.io/gyb-install
#!/usr/bin/env bash

usage()
{
... [pages of script]
...
# Clean up after ourselves even if we are killed with CTRL-C
trap "rm -rf $temp_archive_dir" EXIT

It didn't start, and seems to not have installed either:

>> which gyb
>>

So I tried to get the tar file, but that link leads to a "404 This is not the web page you are looking for" page.

Any suggestions?
