One of the reasons Homebrew just works relative to the competition is because we recommend installing here. Some things may not build when installed elsewhere. However do yourself a favour and use the installer to install to the default prefix.

/sw and /opt/local because build scripts get confused when Homebrew is there instead of Fink or MacPorts, respectively.

/tmp subdirectories because Homebrew gets upset.

Homebrew itself can handle spaces, but many build scripts cannot.
