Subject: requiring standard libs with save level 1

I've set up new version of Ruby from CVS and my programs failed to work.
ruby refuses to require standard libraries. Whats wrong?
Here is IRB snapshot:

irb(main):001:0> VERSION
=> "1.8.0"
irb(main):002:0> RELEASE_DATE
=> "2003-06-06"
irb(main):003:0> $SAFE = 1
=> 1
irb(main):004:0> require 'base64'
SecurityError: Insecure operation - eval

Maybe IRB bug!!
