I installed ncurses in a Centos, the installation was succesful but when i open the script say me

!/usr/bin/env php

Fatal error: Call to undefined function ncursesinit() in /home/august7/publichtml/interactu/Comuny/trace.php on line 11

This script need some aditional library? In this script have this /usr/sbin/traceroute and in the server from SSH say /usr/sbin/traceroute google.com No such file or directory

Also this script call functions not defined, and have not some include() or require() function calling anyother script or library
