Well, the "is old" message was a warning I had added to my own .irbrc. 
Heh. I forgot that.

But that still doesn't explain why 1.8.0 has:

$ irb --version
irb 0.9(02/07/03)

But the latest irb in RAA is dated 2002.09.03.

The date printed by the '--version' option comes from @LAST_UPDATE_DATE 
assigned in version.rb. I checked that the version.rb that comes from 
1.8.0 really does have

   @LAST_UPDATE_DATE = "02/07/03"

whereas the version.rb that comes from RAA has

   @LAST_UPDATE_DATE = "02/09/03"
