Here's the trick i use, download Multiman or any homebrew that come with several pkg in it.
Usually you have, hombrew-3.55.pkg and hombrew-3.55 GH.pkg
First install the -3.55 version, if it works you have kmeaw.
If not, try the other one, it should be working as Geohot/Waninkoko.
Though i can't get for sure how to tell which is Geohot from Waninkoko v1/v2.
Anyway, you should know what to install now.
