If you don't have a valid license during the time of install that has the line:SITEPUBLISHER=true, then Sitepublisher will not be installed along with teamsite. However, if you get a valid license afterwards with sitepublisher enabled, then you can do a manual install of sitepublisher afterwards.
Make sure you get the license and do the SitePublisher install before you install any service packs. Otherwise you will need to uninstall your service packs to install SitePublisher.
