Redmine

I've upgraded to the 1.3 release of redmine from 1.0. I also updated ruby to 1.8.7 from 1.8.6. Lastly I switched from using mongrel to using passenger since we use apache for everything else on our server.

So when I try and run redmine I get the following error... "no such file to load -- bundler"

I'm not sure what to try to resolve this.

Any hep would be appreciated. Let me know if there is more information I can provide to help.
