I realize this is likely a problem with Homebrew, but with a fresh install of Beta 3, there is something going wrong with the Beta 3 Command Line Tools. Even after accepting the SLA it keeps trying to install Command Line Tools over and over again preventing the install of Homebrew. Like I said, probably not a big deal on this side, but I didn't see anything after an hour of searching, so if someone else is having this problem you are not alone!
```xcode-select: error: command line tools are already installed, use "Software Update" to install updates```
