Well, the major difference being that apt is typically run as superuser, where I would presume you're not using sudo with bundle install. Unless there is an escalation exploit, worst case is that the code trashes your user's home folder.
Still, a valid point for the vast majority of other package managers, including apt. At some point, you have to trust somebody though.
