chan_spy how to get that working?

Ok, we are running a callcenter with asterisk (70 seats) and since the E1 was connected to the asterisk machine of the callcenter, I used zapscan and zapbarge for our supervisors to listen to the agents.
Now we have asterisk companywide and the 3 E1s are no longer directly on our callcenter machine, so zapscan and barge do not work anymore.
But there is chan_spy. I read that it was out of the CVS tree and now is back in, but I can not figure out, how to get it installed on my * server.
I have to say, that I am using Gentoo, so I emerge asterisk (1.08), but since I am not a Linux guru (I am more a communication guy), I dont know how to manually incorporate chan_spy.
Is there any possibility to make chan_spy work on my machine. Oh, I used ebuild to manually fetch and unpack the sources, I could not even find chan_spy.c, so now I dont know, how to continue.
Any help would be highly appreciated. Thanks
