Subject: Re: Do I need to upgrade to the latest version of Ruby

use rvm and leave the system ruby alone. rvm is essentially a sandbox
for installing and running different rubies with the added bonus of
gemsets. The other option is to use mac ports to install the various
ruby implementations and run

port -v install ruby19

The only benefit to using your package manager to install them is to
have them available system wide and to automate dependencies and
updates which rvm leaves the user to deal with by hand.

Of course you can do it both ways. But one thing I know for sure. You
never want to remove system installed programs. Usually because some
system installed bit may depend on it. Even in this case where ruby
and rails are installed by apple for marketing to developers and
create appeal for their product amongst web developers.Though I'm sure
we all know that removing rails wont cause OSX to come tumbling down
keeping the original ruby may save you on less headache or reinstall
one day. Though I highly doubt removing the system ruby would really
do any real harm. Just saying.
