AVR Dragon with OS X Intel Machine

Hi -

I've tried a couple different versions of avrdude with my setup 
including 5.3.1 with the osxintelhack (mentioned on this list), as well 
as the latest CVS version, and I still get a hang whenever trying to use 
this emulator/programmer.

Here's the full (yet short) log of what happens when I attempt to 
connect.  Things seem to work on a windows machine through AVR Studio.

$ ./avrdude -c dragon_isp -p m8515 -P usb -Futvvvv      avrdude: Version

Same deal with 5.3.1.  Any suggestions?

Thanks!
