Tvheadend

I can't seem to figure out to get tvheadend installed. I've been able to install other apps like Sabnzbd, SickBeard, etc just fine, but not this.

I've cloned the source from git and have configured it like this:

bash configure \
--disable-avahi \
--prefix=/opt/tvheadend

When I run make I get the following:

NAS1> make

Any ideas?
