ruby on rails って何かなと思って試して見た

t-105@makoto 12:45:56/111208(..misc/rubygems)% gem18 install rails   
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions into the /usr/pkg/lib/ruby/gems/1.8 directory.

上記は、ちょっと (= かなり)古い次の版の時

ruby18-rubygems-1.3.7 Ruby standard for publishing and managing third party libraries

1.8.11 (ruby18-rubygems-1.8.11) にしたけれど、やはり同じ。
