Rubygem

/usr/local/bin/gem:8:in `require': no such file to load -- rubygems (LoadError)
from /usr/local/bin/gem:8

ぐわああああああ！とりあえず慌てず騒がず RHEL なので up2date で zlib をインストール。

$ sudo up2date zlib
->ねえよ

ぐわああああああ！(２回目)あ、あ、わてるな、PATH を通せば行けるはずだ…。

$ vi ~/.bash_profile
-> RUBY_LIB=/usr/local/lib/ruby/gems/1.8
-> export RUBY_LIB

->ばーか

ぐわあああああ！(３回目)

$ cd /usr/local/src/rubygems/
$ sudo /usr/local/bin/ruby setup.rb --prefix=/usr/local
$ gem -v
1.3.4

あ、あれ？
