Is there a way to install this without using Homebrew? I know that the author of it works at Github now, but that definitely shouldn't be the only option..
In this case, you can download the prebuilt binaries from the Github repo page itself under the 'Releases' tab. But as with anything in Brew, if you can't find the installable binary or tarball online yourself, you can simply look at the Brew formula to find the URL and download+install it manually.
