[PlanetCCRMA] Qjack problem

I think I have an incompatibility. My copy of QjackCtl will not communicate with jackd properly. 

I have: 

=====> uname -a 
Linux firewire.ccc.hsd1.comcast.net 2.6.33-1.rt7.1.fc12.ccrma.x86_64.rt #1 SMP PREEMPT RT Fri Mar 12 16:53:00 EST 2010 x86_64 x86_64 x86_64 GNU/Linux 

=====> rpm -qa | grep jack 

=====> rpm -qa | grep ffado 

=====> rpm -qa | grep 1394 

The problem is that Qjack tries to start jackd (unsuccessfully) with: 

# jackd -R -dfirewire -dhw:0 -r48000 -p1024 -n3 

jackdmp 1.9.4 ... 
Unknownage with option 'd' 
Options for driver 'firewire': ... 

but jackd does not like the -d in front of hw:0 . If I type on a command line (omitting the -d): 

jackd -R -dfirewire hw:0 -r48000 -p1024 -n3 

then jackd starts normally. If I then tell Qjack to start jackd, it finds jackd already running and controls it just fine from then on. I can start japa and ardour and patch them to my Edirol FA-101 in the Qjack connect window (it all works great!). Qjack will also stop jackd correctly. 

Have I got the wrong version of something? Did jackd forget his interface options?
