Default Virtual ground in Cmoy amp

Hello guys, i`m trying to put together a headphone amp by using Tangentsoft`s approach ( http://tangentsoft.net/audio/cmoy-tu...angent-sch.pdf ) but i fail to understand how to wire the virtual ground. I just can`t figure out where to connect the wires. I made a Fritzing design of where i am now. If anyone could tell me what to do with the wires hanging around in the picture( https://dl.dropboxusercontent.com/u/45794359/amp_bb.jpg ) i would really appreciate it. If someone finds any other mistakes please feel free to point them out.

I didn't verified the whole scheme but "virtual ground" is the ground, the jack ground pin should be connected to it.

The red arrow I added to your image is the virtual ground point. So that point needs to connect to all other points in the schematic with the ground symbol.
