Please Help Me! :

I am tried to install OTRS in CentOS 4.3. but in the step 2 I have this messaje:

Kernel/Config.pm isn't writable!  If you want to use the installer, set the Kernel/Config.pm writable for the werserver user! Can't open /opt/otrs/Kernel/Config.pm: Permission denied

I reviewed permission for this file but it´s right.
