PostgreSQL 6.5.3 on SuSE 6.1

Hi list members:
I am currently using PostgreSQL 6.4.2 on SuSE 6.1.  This version came with
the SuSE disks. Recently, I downloaded and compiled the source from the
pgsql ftp site, but postgres does not run and says that a file called
libreadline.so is needed to run.  This file is not on my computer. Is
there a way to make postgres run without this file on this distribution?.
Are there RPMs for SuSE 6.1?
Any help is appreciated.

Thanks,
Vegeta
