In chapter five of the book Build Your Own Ruby on Rails Applications,  
when I entered the rake db:migrate command in the Ruby console, I got  
the following message back:

`:
Warning require_gem is obsolete. Use gem instead.
`

What does this mean, and what should I do? Was the rake db:migrate  
command executed? If I want to update require\_gem, what do I need to  
do?

Thanks in advance.
