[CentOS] open webmail error

Hi,

I installed openwebmail on centOS 4.4 using tarballs

CGI.pm-3.05.tar.gz MIME-Base64-3.01.tar.gz libnet-1.19.tar.gz Text-Iconv-1.2.tar.gz openwebmail-2.52.tar.gz

and fianlly I did the below

/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init

Then I browse as below

http://IP/cgi-bin/openwebmail/openwebmail.pl

then I got the below error.

Please execute '/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init' on server first!

then, I again issued that command many times.

/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init

/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init

But I still get the same error. Can you help me to solve this?
