Leopard で MacPorts から rubygems がインストールできない

Macbook に rascut を入れようと思って、ports から色々入れようとしたら、

% sudo port install rb-rubygems
・・・
./lib/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- socket (LoadError)

でしくじる。
#15254 (rb-rubygems 1.1.1_0 fails on Staging phase) – MacPorts で上がっていた。
そして Leopard には rubygems が /usr/lib/ruby/gems に入ってることに気づいた。

（追記 2009/01/09）
上記の#15254 (rb-rubygems 1.1.1_0 fails on Staging phase) – MacPorts は #15177 (ruby-1.8.6-p111+ doesn't work with autoconf-2.62) – MacPorts の duplicate であり、#15177 がFixed なので現在は直っているとおもわれます。
