[typo] typo 5.1.1 to 5.2 upgrade

[Chris Dagdigian]

Hello,

When I follow the upgrade instructions for "gem install typo" I seem  
to get the edge 5.2.98 version which gives me install gripes like this:

...

Do I have a gem setting or ENV wrong that puts me on the edge track?  
How do I tell gem that I want the stable 5.2? Sorry for the novice  
question.
