readline install questions - Mailing list pgsql-general

I am attempting to install postgresql7.4.5 on OSX 10.3.5 and have
questions about
readline.

For use with Python, I have readline.so installed in
/Library/Python/2.3/.

- Is this "manifestation" of readline sufficient/appropriate for
postgres?

- If not, what do I need and where do I get it from?

- If readline.so is sufficient/appropriate, where should I copy it to
so that
   configure can find it?

- Conversely, where is the path specified so I could point it to the
file that
   already exists?

Thanks in advance!
Scott
