Hi.

I am pretty new to ruby (and those gems) and rails… Until now I  
thought that all rails application have some kind of integrated  
version management (RAILS\_GEM\_VERSION in Rails 2 and gem ‘rails’ in  
Rails 3). And therefore I thought that having Rails 2 and Rails 3 in  
the same gem repository (in my case gemset under rvm) wouldn’t be a  
problem. But during installing Redmine I figured out that it can lead  
to problems. When Rails 2 and Rails 3 are in the same gemset Redmine  
cashes on some pages that when only Rails 2 is in the gemset doesn’t  
happen. So it seems that Redmine does use some things of the Rails 3  
libraries even though it specifies the correct RAILS\_GEM\_VERSION of  
2.3.5. Why that?

Best regards,  
Kai
