You are probably looking for a package name "MYSQL-devel" or MYSQL-dev". Just toss those names through rpmfind.net or rpm.pbone.net and you'll probably find it. I'm not that familiar, but does RedHat use yum like fedora, because if so, that whole thing simplifies to something like:

yum install MySQL-devel
