[syslog-ng] Can't build syslog-ng RPM

I'm trying to build the syslog-ng RPM and I'm having an issue with the libnet-devel package. I've tried searching for it and I can't find a devel package from Fedora, CentOS, or RHEL. I found the libnet-devel page but the project appears to have forked now so I'm no longer sure if its still good to use. Just in case you're wondering why I'm trying to build from source, the current packages are built for amd64 and I'm running x86_64 on an Intel. Any help with how I can get libnet-devel installed would be much appreciated. Thanks.
