When trying to install setuptools 0.6c8 on jython2.5a1+ (mac osx 10.5.4/jdk 
1.5) I'm getting an error. How to reproduce:

 - Get the installer from http://downloads.sourceforge.net/jython/jython_installer-2.5a1.jar
 - Install it (in my case in ~/Sites/jython2.5a1+)
 - cd ~/Sites/jython2.5a1+
 - wget http://peak.telecommunity.com/dist/ez_setup.py
 - ./jython ez_setup.py
 - Results in the following error:
