Also, I checked the gems folder C:\ruby\lib\ruby\gems\1.8\gems and it
shows the previous gems along with the new gems for Rails, e.g., it has
actionpack-1.13.1 and actionpack-2.1.0, activerecord-1.15.1 and
activerecord-2.1.0, and so on, you get the idea.
So my question is that normal? Should the old gems still be there? If
not, how do I remove them? Thanks in advance for your help.
