I'm trying to do this http://php.webtutor.pl/en/2011/04/25/mod_rewrite-and-hiphop-for-php-on-apache-web-server/
But the yum -y install httpd httpd-devel
gives -bash: yum: command not found
.
I'm on 12.04.
I already have apache installed. I just don't know how to get the "development tools".
Please show me how. Many thanks in advance!
