Ports Tree, Installing
From FreeBSDwiki
When you installed the OS, you were given the option to install the ports system. If you said no but have since thought better of it, you can go into sysinstall and install it (in the Distributions sub-menu). To install a port, you must first become root and find it:
dave@samizdata[~]% su - Password: samizdata# cd /usr/ports
You can search the ports collection for ports to install by browsing through the categories, or you can use "make search" like so:
samizdata# make search name=mozilla | more
or
samizdata# make search key=browser | more
