Hello,

On a debian Etch, I suddenly get this error : 

/usr/bin/gem:11: undefined method `manage_gems' for Gem:Module (NoMethodError)

Message:
You haven't been paying attention to the install messages, at the end it 
printed out where it installed gem, which was likely `gem1.8` or `gem18` at the 
end of the upgrade, not `gem`.  The last half of this blog post will help you 
out:

Hi Dan,
Thanks for the quick answer.

I get this error when I do a simple "$ sudo gem list" or "$ 
sudo gem update".

I don't maintain any gem so I don't really get what you 
mean by "It should be removed from your gemspec".

Cheers
Jérémy

Message:
The manage_gems method had been deprecated for quite some time and was finally 
removed. It should be removed from your gemspec.

Or, if you prefer to maintain backwards compatibility, you can do this:

Gem.manage_gems if Gem::RubyGemsVersion.to_f < 1.0

Regards,

Dan
