<p>I've been unsuccessfully searching for a way to install <code>make</code> utility on my CentOS 5.2. I've looked through some RPM repositories and online, with no avail. Installing <code>gcc</code>, <code>gcc-c++</code> didn't help! Package <code>build-essential</code> is not made for CentOS/RHEL. I have RPMFORGE repo enabled in YUM.</p>

I just double checked and CentOS 5.2 already includes make!
I found it also in one of the online mirrors, if it is easier for you:
http://centos.cogentcloud.com/5.2/os/i386/CentOS/make-3.81-3.el5.i386.rpm
if you installed the 64 bit version:
http://centos.cogentcloud.com/5.2/os/x86_64/CentOS/make-3.81-3.el5.x86_64.rpm
