Thank you all for your help. Selinux was the problem. Here is how I solved it:
# yum install /usr/sbin/semanage
# semanage boolean -m --on httpd_can_network_connect_db
# semanage boolean -m --on httpd_enable_cgi
# semanage boolean -m --on httpd_can_sendmail
Then the install.php ran fine and ended with Instalation completed successfully.
This is the install script that was part of the Git repository. I now have Moodle 2.4 running in a virtual CentOS 6.4 64bit server on a Windows 7 64 bit host using virtualBox. I am using 96% of my root file system so I plan to expand the storage allocation and gurn GParted live to adjust the partitions.
