aha! you're installing from source (which is why it's .src.rpm file). in redhat, that was installed correctly, but it's not where you want it. instead, it's in /usr/src/redhat/SOURCES. i think in order to use it, you need to run make on it, which isn't really practical when you're installing make for the first time, is it?
i'd suggest just to get the make RPM itself... make-3.79.1-5.rpm should probably be the name. make sure you don't have any .src extension in the actual filename.
you can get the make rpm (and more) from
www.rpmfind.net. on the list of stuff that comes up, get the RedHat i386 file... it's highlighted some funky color (green, i think)
hope that helps
