[CentOS] Anyone have tora running on CentOS 4.X talking to an Oracle DB?

I was looking for a tool to access an Oracle database (the lack of  
readline support in SQL*Plus is really annoying) and stumbled across  
tora.  I successfully did a "yum install tora" , but I can not access  
my Oracle database, as expected after reading the following in the  
RPM description:

    Tora ("Toolkit for Oracle") is a GUI-based database development
    program, offering SQL worksheets and a database browser.

    Please note that the Oracle plugin is not shipped.

I can't find any instructions on how to  get and/or install the  
Oracle plugin.  Most Google queries I found suggest building tora  
from scratch, but I'd rather stick with using the RPM if possible.   
In case it matters, I'm trying to access an Oracle 10g instance that  
is running on a CentOS 4.4 system.

Are there any other tools people use to access Oracle instead of  
SQL*Plus?  I'll use anything that provides decent command line  
editing (e.g. readline support) and can automatically figure out the  
size of my terminal.  SQL*PLus is pretty brain damaged in those  
departments.

Thanks,
Alfred
