I ran into a similar problem (CGI script unable to access the network) and discovered that it stemmed in my case from SELinux, the NSA's secured Linux kernel. It is built into Fedora from core 3 onwards, as well as some other distros, and is installed on many individual servers besides. If you determine that you are running selinux (try the command /usr/sbin/selinuxenabled (default path). If it returns 0, you have it), it has a variable called httpd_can_network_connect. Set this to 1 and selinux will stop blocking CGI network connections.
