# Install all our ruby dependencies in an isolated environment. We
# depend on gem being installed globally, but not bundler. (Go
# developers sometimes manage to install
# https://github.com/golang/tools/tree/master/cmd/bundle in a location
# that conflicts with the ruby tool of the same name)

# HACK: Make has a fast path and a slow path for command execution,
# but the fast path uses the PATH variable from when make was started,
# not the one we set on the previous line. In order for the above
# line to have any effect, we must force make to always take the slow path.
# Setting the SHELL variable to a value other than the default (/bin/sh)
# is one way to do this globally.
