Subject: Re: Ruby 1.9.2 is released

Dear everyone having Gem.path issues:

I compile manually. Install to /usr/local. Pretty standard. I had 1.9.2 
preview 3 installed.

I installed 1.9.2p0, got the Gem.path error.

Here's the simple solution that worked for me: nuke the gems, make 
install again.

sudo rm -rf /usr/local/lib/ruby/site_ruby/1.9.1/*ubygem*
cd your-ruby-src-path
sudo make install  # assuming you have it compiled from before
