unable to install 2.1.1 on cpanel server

[wsani]

I tried to install version 2.1.1 but here is what I get:

error: Failed dependencies:
httpd is needed by Sitebuilder-2.1.1-rhel4.build051014.20.i386
php >= 4.3 is needed by Sitebuilder-2.1.1-rhel4.build051014.20.i386
php-mysql is needed by Sitebuilder-2.1.1-rhel4.build051014.20.i386
Suggested resolutions:
httpd-2.0.52-19.ent.i386.rpm
php-4.3.9-3.8.i386.rpm
php-mysql-4.3.9-3.8.i386.rpm

Then I try:

rpm -Uhv Sitebuilder-2.1.1-rhel4.build051014.20.i386.rpm --nodeps

Preparing... ########################################### [100%]
package Sitebuilder-2.1.1-rhel4.build051014.20 is already installed

I tried to rpm -e Sitebuilder-2.1.1-rhel4.build051014.20.i386.rpm --nodeps

and it says: error: package Sitebuilder-2.1.1-rhel4.build051014.20.i386.rpm is not installed

Has anyone actually gotten 2.1.1 installed on the cpanel server? I know version 2.0.0-rhel3.build050606.17 works but what about this other one?
