I discovered a bug when trying to use virtualenv with Jython 2.5b3.  I
installed it as a standalone jar and got the same error on both Mac OS X
and Ubuntu Linux 8.10.  Here is the simplest code to get the error:

~/Programming/Jython/jython2.5b3 jimsize$ java -jar jython.jar 
Jython 2.5b3 (Release_2_5beta3:6092, Mar 10 2009, 15:34:57)
