They aren't installed with the main JFBConnect component, but are included in the package you downloaded. When you first unzipped the file, there are other files. One of those is the jfbconnect_social_modules_xxx_unzip_first.zip file. Unzip that one and you'll see the whole slew of modules.
We're working on a better installer for the future as the installation process and finding everything is definitely our weakest point right now...
Hope that helps,
Alex
