I just installed jython via yum and get the following.

    ebrunsonlx(~)$ jython
    Jython 2.2.1 on java1.6.0_18

Most everything readline related seems installed:

    ebrunsonlx(~)$ sudo yum list *readline*

ldd doesn't show any linkage failures in any of the shared objects 
distributed with libreadline-java.

Can anyone confirm the error is not just on my system?  What's the 
protocol for further investigation?  Would it be inappropriate to 
contact the maintainer directly or should I just file a bugzilla?

Thanks,
e.
