[PlanetCCRMA] jack problem after recent system upgrade

[Peter Lutek]

greetings!

i'm on an fc3 planet laptop, which was working flawlessly, until i 
recently did a bunch of available upgrades. now jack won't start:

 >/usr/bin/jackd -R -dalsa -r44100 -p128 -n2 -D -Chw:1,0 -Phw:1,0
jackd 0.99.36

is this possibly related to the pam upgrade? any other clues?

thanks very much.
