Newbie Install Cannot Make Clean or Make Install?

When I run the command make clean or make install, I get this?

[root@asterisk asterisk-1.4.10]# make clean
-bash: make: command not found

What am I missing here?

As i research more I find out I need this

yum -y update
yum -y install gcc gcc-c++ libtermcap-devel kernel-devel bison openssl-devel mysql mysql-server mysql-devel
