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

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.
