If the former, you probably have more than one named executable - with the old one earlier in your PATH. "which named" should help. If the latter, did you remember to restart named? And did the restart succeed? And does your startup process have the same PATH as your terminal? (Often they do not.) Re-read the instructions - and pay special attention to how you run configure. The default is to build/install in /usr/local/*bin - which is not the default for most distributions' startup files. I strongly recommend keeping track of each step as you build (a big scrollback buffer helps). Either write your own instructions, or turn it into a script. There are enough steps that it's easy to make a mistake - and you will be re-building bind again to upgrade. Plus, if you ask for help, you will be able to provide the details of what you did. Without details of what you did and what you see, people can't provide specific help. Note that RedHat usually has a number of patches (often for SeLinux and systemd) that you won't get if you build yourself from ISC sources. Or remove bind and switch to the RedHat version. You're paying RedHat to do the maintenance, so unless you have local patches or very special requirements, you might as well let them do the work. Typically, if you really need the latest from ISC on RedHat you're better off getting the SRC RPM from RedHat & modifying the rpmbuild config file to fetch the latest ISC source, then build RPMs. If you stay with the same ISC code stream, you won't have too many patch conflicts to resolve. After you've done this once or twice, you'll want to revisit you need for local changes - either decide they're not that important, or offer them to ISC. Maintaining a private version is work.
