I've been having a nightmare getting Ruby and RubyGems playing nicely on my Mac. I wanted to get the latest (stable) version of Ruby so the one that comes pre-installed with OS X was no good. Somehow, when I first tried to install Ruby and RubyGems using DarwinPorts I ended up with ruby in /usr/local and gem in /opt/local. This caused issues from my terminal since I didn't have both these in my path - so this was the first thing I had to fix (by adding some paths to my .profile file).
One annoyance while I was doing all this was I was having to run the port and gem commands as an administrator. The login I use for my development work isn't an administrator so I have to keeping switching to an admin account in my shell and invoking the commands that way. However, the way I understand it, that means any environment variables ($PATH and $GEM_HOME are the two that seem to have reared their heads for me here) are now the admin users'. I don't really want to have to have my dev user's environment set to the same as the admin one. I'm thinking that I've got into a mess here and I need to do one of two things:
1. Do a private install of Ruby and RubyGems just for my dev user, or
2. Make my dev user an administrator.
I'm leaning towards 1 at the moment.
Recently I installed NetBeans, hoping to use it to debug my Ruby apps but I got a problem with RubyGems again. The issue was that it couldn't find the gem command, presumably because the modified path in my .profile file isn't picked up my OS X.
