Rails Console (v1.2) won't load

Hi - just upgraded to rails 1.2 and the console script is failing to
load under ruby 1.8.5-p2. Any one seen this before? (Every thing
else is running fine; hmmm...) Thanks for any help you can lend.

Regards,

Ken

Neglected to mention that I'm running on Ubuntu linux w/a locally
built Ruby.

seems like you've built ruby without gnu readline
i don't have ubuntu but google suggests ([1,2])
it does not have the readline library
or development headers installed by default.
