FreeNAS community member DrKK created a tutorial on how to install Owncloud in FreeNAS. Click play below to learn:

This is an oft-requested tutorial from the FreeNAS community. We go through, stream of consciousness style, from a bare FreeNAS, and fully install and configure a working OwnCloud server. I also show the installation and setup of the client software in Windows. It is a long video–around 40 minutes–but I think is worth the investment of time. Those just wanting to learn how to install OwnCloud in FreeBSD itself, or lighttpd in FreeBSD itself, may also find the video useful.
