Your shell has been configured to use Homebrew's build environment: this
should help you build stuff. Notably though, the system versions of gem
and pip will ignore our configuration and insist on using the
environment they were built under (mostly). Sadly, scons will also
ignore our configuration.
When done, type `exit'.
