There are several RPM builds of haproxy that can be found throughout the Internet. There are GitHub repositories with customized .spec files to build your own RPM. In fact, there is an haproxy.spec file that may be found in the official .tar.gz file under examples. However, here is a unique way to build one as close to the original, haproxy-1.5.4-2.el6.rpm, official build found in the CentOS 6 base repositories.
Using rpmrebuild, it was plain that the official build used this source, haproxy-1.5.4-2.el6.src.rpm.
yum install -y rpm-build rpmdevtools pcre-devel openssl-devel zlib-devel redhat-rpm-config gcc gcc-c++ make libstdc++-devel wget rpmlint vim rpmdev-setuptree
Create your build environment
rpmdev-setuptree cd ~/rpmbuild/SOURCES/

If you attempt to manually build from source ip6range, you may be presented with many, many errors and no build.

For reasons that can be found elsewhere, the structure of one of the helper files and that of the ip6range.c file had changed. Do this to fix it and use make to build it. Enjoy.
