My luarocks installation on OS X comes from the lua installed via

Error: Your user does not have write permissions in /usr/local

Homebrew requires /usr/local to be writeable; Homebrew recommend fixes:

sudo chown -R $(whoami) /usr/local


sudo chgrp -R admin /usr/local
sudo chmod -R g+w /usr/local

You will need to do one of these to continue using Homebrew. LuaRocks specific options, such as using a local tree, may be fine in general, but you'll still have the Homebrew problem.
