problems with lttng-0.5.1/ltt-control-0.5/linux-2.6.14.1

I am trying to use lttng with a Linux 2.6.14 kernel. I applied 
patch-2.6.14-lttng-0.5.1. I compiled ltt-control-0.5-06042006. However, 
I'm getting some run time errors. I've not used lttng before, so I'm 
probably just misunderstanding something. Any help on this would be most 
welcome.

When I run the command:

sudo lttctl -n trace -d -l /media/debugfs/ltt -t /tmp/trace

I get the error:

Linux Trace Toolkit Trace Control
Controlling trace : trace
Create Trace Error: Failed to send netlink message: Connection refused

Thinking that it may need some sort of daemon, and noticing an lttd 
command, I then tried:

sudo lttd -t /tmp/trace -c /media/debugfs/

Error in getting the number of subbuffers: Inappropriate ioctl for device

I presume the ioctl error is the key. Here is the relevant configuration 
from my kernel .config file:
