can't find Bundler

I'm trying to get bundler working on my Dreamhost account. when I type bundle update in my application I get

-bash: bundle: command not found

I installed bundler 1.0.15 in gem bundler

gem environment results in:

I configured my .bashrc

# ~/.bashrc: executed by bash(1) for non-login shells.
PATH=$PATH:/usr/lib/ruby/gems/1.8/bin;/home/myuser/gems/bin

and my .gemrc

gemhome: /home/myuser/gems
gempath:
- /home/tarscher/gems
- /usr/lib/ruby/g开发者_高级运维ems/1.8

UPDATE When I go into /home/myuser/gems/binwhere the bundle script is located dir and type bundle I also get -bash: bundle: command not found .

Someone knows why bundler isn't found?

Thanks

There's an error here:

PATH=$PATH:/usr/lib/ruby/gems/1.8/bin;/home/myuser/gems/bin

The paths must be separated by :, not ;
