I just upgraded Ruby 2.0.0-p247 to Ruby 2.0.0-p353 using `rbenv install 
2.0.0-p353` but now I don't have any gems for that version. I'm new to 
Ruby is it honestly required that the complete gemset has to be 
reinstalled for every point release upgrade or is there a way to 
copy/transfer/install the gems from the prior point release? Perl/CPAN 
was so much easier :(

gvim
