installation for mailscanner

[mailadmin at baladia.gov.kw]

Dear All,

I am new to mailscanner n have gone throght the docs..
but wanna clear a few doubts b4

the following have already been installed

Centos 4.5
perl-5.8.5-36.RHEL4
spamassassin-3.2.1-1.el4.rf
clamav-0.91-1.el4.rf

I downloaded the (install-Clam-0.91-SA-3.2.1) and read the install.sh
script says
--------------------------------------------------
'If you want to use MailScanners support for Clamd (virus-scanning'
echo 'daemon) then I recommend you cancel this script now (press Ctrl-C)'
echo 'and install the RPMs for clamav, clamav-db and clamd from'
echo '     http://dag.wieers.com/rpm/packages/clamav'

---------------------------------------------------------

so i did the above and hence have the above

but later in the install script i see the followin

----------------------------------------------------------------------
 echo
  echo '*** IMPORTANT ***'
  sleep 2
  echo I could not find your MailScanner virus.scanners.conf file.
  echo Please locate the file yourself and edit the clamav and clamd lines
in it.
  echo On those 2 lines, the path at the end of each line needs to be
$CLAMPRINT.
-----------------------------------------------------------------------

now im confused ..

1) do i ned to run the install.sh script in /install-Clam-0.91-SA-3.2.1
directory since it will install not only clamav but also spamassassin as i
dont see any clamav.conf file. OR do i have to install the mailScanner
software first

appreciate if you can tell me the steps

also i see that
echo 'Now you need to install:'
echo '1) Razor-agents-sdk and Razor2 from http://razor.sourceforge.net/ and'
echo '2) DCC from http://www.rhyolite.com/anti-spam/dcc/ and'
echo '3) Rules_Du_Jour from http://www.fsl.com/support'

how do i know if my system has already the above installed .


Thanks and Apprecite
