That depends largely on your setup.  In the general case, yes, look into
rvm (Ruby Version Manager) for managing that.  If your talking via
passenger, then the answer is no(ish), the same passenger process cannot
run multiple versions of Ruby. Without further details on your setup,
that's really all the help I can give.
