Warning: Some directories in /usr/local/share/locale aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:

Warning: Some installed formula are missing dependencies.
You should `brew install` the missing dependencies:

    brew install apple-gcc42

Run `brew missing` for more details.

Warning: Homebrew's sbin was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting the PATH for example like so
    echo export PATH='/usr/local/sbin:$PATH' >> ~/.bash_profile
