[dennou-ruby:003292] ruby-lapack の ruby 1.9.1 対応.

[Youhei SASAKI <uwabami@xxxxxxxxxxxxxx>]

西澤様: 佐々木です.

ruby-lapack のパッケージを作成しています. 

バイナリパッケージ自体は作成できたのですが ruby1.8 の場合と ruby1.9.2 の
場合で samples/dsyevr.rb の結果が異なるので, 気になっています.  

# ちゃんとドキュメント読むべきなんでしょうけれど...

変な所は 

 % ruby1.9.1 -d -w dsys
 - snip -
 NArray.int(12):
 [ 1, 3, 1, 3, 1, 3, 1814901814, 2020961897, 1836412463, 1815049586, ... ]
 - snip -

で, あからさまに変な所を参照していそうです.
