I installed Ruby Enterprise 1.8.7 on a Ubuntu server that already has the standard Ruby 1.8.6 install. They both put the same local user gem directory /home/{username}/.gem/ruby/1.8
in their GEM PATHS. Is this safe and proper?
If not, is there a way to alter the GEM PATH of Ruby Enterprise 1.8.7 (but not Ruby 1.8.6) through an environmental variable so it doesn't include /home/{username}/.gem/ruby/1.8
but instead something like /home/{username}/.gem/ruby/1.8.7
?
