Hi,  
there must be some configuration mistake but can someone help me out?  
I have ruby, gem, rails and such installed.  
version  
ruby: 1.8.4  
gem: 0.8.11  
rails 1.2.2

If I do a

rake rails:update

I get the following:

Rake aborted!  
undefined method `gem’ for main:Object

I get the same message when doing just  
rake

any ideas?  
Is there a problem with my path?

thanks in advance.

I know the newest version of rails requires the newest version of  
rubygems,  
this is where Object#gem comes from.

thanks in advance.

yes, you need the latest version of rubygems.

Do:

sudo gem update --system

and consult the rubygems 0.9.2 release notes if you have trouble.
