Title: Make sure we have a non-empty $PERLBREW_PATH

Issue when installing for a multiple user setup and customizing PERLBREW_ROOT path. If PERLBREW_ROOT isn't set we will have an empty PERLBREW_PATH for a user trying to source ${PERLBREW_ROOT}/etc/bashrc for the first time unless there is a perl version installed?
