[linux-audio-user] running freebob enabled jackd with M-Audio FireWire Solo

I hope this isn't considered a cross-post, as I've already posted
something similar to freebob-dev.  But I think I may be beyond
compile/install issues and on to basic user issues.  

I've managed to get freebob enabled jackd to build and run on my system,
Ubunto Dapper 64bit version.  I can run the daemon, but can't seem to
get any jack clients to connect to it.  


When I run jackd, I see this EXCITING output:

sudo jackd -v -R -P70 -dfreebob -r48000 -p512 -n2

I noticed the line:
Compiled modules:  (FLAC) (Jack) (Alsa) (OSS) (LRDF)

I didn't think I would have to recompile programs that use the jack
daemon.  Am I wrong?
