I'm sorry they didn't work for you, but under 7.1 they worked like a charm for me, maybe something in your Linux install? You can try these Redhat 6.2 instructions from http://www.wgbh.org/doc/redhat.html
they are the same instructions I used for my 7.1 install and were originally written by the old Arsdigita for installing ACS and Oracle.
Or, I have some instructions at http://pcs-sc.com:8000/etp/lamps/rhlinux , for Red Hat 7.3, just don't do the Web Server, php or Mysql stuff. The rest of the instructions should work fine for installing either 3.2.5 or OACS 4.5.
Good Luck and if you have further questions just ask,
