Hi Spencer,
Thanks for looking into this.
In light of your thoughts, it seems that the problem is due to the
fact that I was unwittingly running chuck version 1.2.0.5. A quick
check shows that 1.2.0.5 is ppc only. Sorry to be a knuckle-head.
The only weird thing remaining is that since I ran the latest
Software Update (Oct. 1), I can't get the error message to recur....
not that that is a problem, but it is curious.
In any case, if you are still interested, my machine gives the
following:
~> file ./chuck-1.2.0.7-exe/bin/chuck
./chuck-1.2.0.7-exe/bin/chuck: Mach-O universal binary with 2
architectures
./chuck-1.2.0.7-exe/bin/chuck (for architecture ppc): Mach-O
executable ppc
./chuck-1.2.0.7-exe/bin/chuck (for architecture i386): Mach-O
executable i386
~>file ./chuck-1.2.0.5-exe/bin/chuck
./chuck-1.2.0.5-exe/bin/chuck: Mach-O executable ppc
~>file System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/

universal binary with 2 architectures

Thanks again,
