I see someone else is having problems updating to gem version 1.3.1 on  
Ubuntu 8.04. But my problem is different. I’ve updated OK and in the gem  
list --local I see ruby-gems-update 1.3.1 but gem -v still returns  
1.2.0. That’s what’s setup in the environment. So now when I try to do  
anything that requires gem version 1.3.1 it doesn’t work.

If I try gem update --system it says there’s nothing to do, it’s all  
uptodate.

Any idea what could be wrong? If it’s just the environment variable,  
where do I set it so that I get the right one after a reboot?

Sorted! I looked at [http://www.rubygems.org/read/chapter/3#page14](http://www.rubygems.org/read/chapter/3#page14)

and then used the hint to run

gem install rubygems-update  
update\_rubygems

It all worked fine after that.
