Brew: Failure while executing: /usr/bin/otool

Please follow the general troubleshooting steps first:

• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed as many issues as possible and retried your prior step?
• [ ] If you're seeing permission errors tried running sudo chown -R $(whoami) $(brew --prefix)?
  

  Bug reports:

Running brew doctor returns the following error on macOS Sierra (10.12 Beta, build 16A201w)

Error: Failure while executing: /usr/bin/otool -L /usr/bin/install_name_tool

Ran brew update twice, no change in behavior. I know that beta OS's are not supported, I'm just putting in a bug report :)

Run xcode-select --install.

That fixed it, thanks! Looks like I needed to reinstall it.
