MacでScalaをインストールしてみる

scala mac

Mac Snow LeopardにScalaをインスコした時のメモ。



Scalaが気になって気になってしょうがないのでとりあえずインストール。
MacPortでインストールすればいいんじゃね?って軽い考え。

% sudo port install scala
Password:
--->  Computing dependencies for scala
--->  Fetching scala
Error: Please one of the numbered scala* ports instead.
Error: Target org.macports.fetch returned: obsolete port
Error: Status 1 encountered during processing.
Before reporting a bug, first run the command again with the -d flag to get complete output.
zsh% scala
zsh: command not found: scala


とりあえず失敗orz
scalaじゃインストール出来ないっぽい。
