According to the manual, if I call ruby this way

```
 ruby -rubygems script_that_uses_gem

```

require\_gem is not needed, plain require is enough.

This indeed is working as documented with WWW::Mechanize, but not  
with ActiveRecord, which loads fine with require\_gem. Is this  
something known?

Running:

ruby 1.8.4 (2005-12-24) [powerpc-darwin8.3.0]  
RubyGems 0.8.11  
activerecord (1.13.2)

Make sure you say: require ‘active\_record’  
Rather than: require ‘activerecord’

“activerecord” is the gem. “active\_record” is the file to be required.
