What is the problem?

Installing KnowledgeTree 3.7 on a Red Hat server can sometimes encounter a conflict if Zend Server installs PHP 5.3.  In this case, the user will see conflicts similar to these when running the install script.

2. Uninstall Zend Server PHP 5.2

# yum -y remove zend-server-php-5.2 && yum -y remove `rpm -qa|grep zend|xargs`

3. Uninstall Zend Server PHP 5.3

# yum -y remove zend-server-php-5.3 && yum -y remove `rpm -qa|grep zend|xargs` 

4. Do a "yum clean all" to clean the rpmdb

# yum clean all

5. Install KnowledgeTree again excluding any Zend Server PHP 5.3 calls

# yum install knowledgetree --exclude="zend-server-php-5.3, mod-php-5.3-apache2-zend-server"

The install should proceed as expected.
