I am getting this error with Rails 1.2.3, while I was trying to change  
session from active\_record\_store to use memcache-client 1.3.

Here is my error, I have checked that  
actionpack-1.13.3\lib\action\_controller\session\mem\_cache\_store.rb is  
present. I tried everything and I am completely stuck. Please help!  
Greatly appreciated.

thanks a lot!
