Having trouble updating Gems; need to change write permissions on directory

Hi–

I just updated to Rails 2.2.3 last night. Wanted to develop a new app
today but got message that I needed to update Gems from 1.3.1 to 1.3.2

So, I ran Terminal and entered the gems update --system command. I got
message returned saying " While executing gem …
(Gem::FilePermissionError) You don’t have write permissions into the /
Library/Ruby/Gems/1.8 directory"

So I went into all those directories and changed write permissions,
including all the parent directories, and then rebooted the computer
(MBP running Leopard). When I ran the same command, I was returned the
same message.

What am I doing wrong?

TIA

If this were Ubuntu I would say that you need to use sudo, and it is
gem not gems, so
sudo gem update --system

If your OS does not use sudo then maybe you need to be root or
something.

Mac OS X uses sudo in the same way that Ubuntu does. The OP should have
done this instead of changing directory permissions.
