I’m trying to get both ruby1.8.5 and ruby1.8.6 installed on the same  
machine, but I’m running into problems now finding gems.

I’ve got the libs for 1.8.5 in  
/usr/local/ruby/site\_ruby/1.8.5

And for 1.8.6 in  
/usr/local/ruby/site\_ruby/1.8.6

I downloaded the gems tgz, unzipped it and ran setup.rb with ruby1.8.5

It seems to have installed gems in /usr/local/site\_ruby/1.8 so when I  
try to require a gem it fails.

Is there a way to fix this? Is there a reasonable way to share the  
gems between 1.8.5 and 1.8.6?
