OSX 10.5でcaty-consoleが動かない件への対処法

    def __init__(self): #, encoding):
        self.encoding = locale.getpreferredencoding()
        if self.encoding == 'X-MAC-JAPANESE':
           self.encoding = 'ascii'
        self.out = codecs.getwriter(self.encoding)(sys.stdout)
        self.input = codecs.getwriter(self.encoding)(sys.stdin)

$CATY_HOME/python/caty/shell/system.py です。Python on OSXではよく起こる問題らしい（google:LookupError unknown encoding X-MAC-JAPANESEを参照）。エラー内容は：

$ python caty-console.py 
Traceback (most recent call last):
  File "caty-console.py", line 9, in <module>
    caty.shell.console.main()
  File "./python/caty/shell/console.py", line 140, in main
    CatyShell(site, wildcat).cmdloop()
  File "./python/caty/shell/console.py", line 19, in __init__
    stream = StreamWrapper(StdStream())
  File "./python/caty/shell/system.py", line 17, in __init__
    self.out = codecs.getwriter(locale.getpreferredencoding())(sys.stdout)
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/codecs.py", line 978, in getwriter
    return lookup(encoding).streamwriter
LookupError: unknown encoding: X-MAC-JAPANESE

ということで、Catyスクリプト試し中...
