Error when compile source code

Hello,I'm trying to compile source code for Nmap.
My $PATH /usr/sbin:/usr/bin:/usr/openwin/bin:/usr/ucb:/usr/local/bin:/usr/css/bin

I type ./configure and all goes great.When I type ./make or ./make it says make not found.Why?I need a correct path for make?Thanks in advance.

Sun stashes their "make" executable in /usr/ccs/bin, however you can try "/usr/ccs/bin/make".

This works
