CentOSのrbenvが古そうだったのでupdate
まずは
たんに，
rbenv update
しても
> rbenv update
Updating rbenv
| fatal: unable to access 'https://github.com/sstephenson/rbenv.git/': SSL connect error
Updating rbenv-update
と怒られる．
解決策
そこで，
> cd ${rbenv root) #=> /usr/local/rbenv
> git remote add origin git@github.com:sstephenson/rbenv.git
> git pull origin master
とします．何，普通にgitの使い方．そうすると，pluginsに必要なcommand群がinstallされます．そうしておいて，
> rbenv update
