Yes, there is something that is making hdiutil think that the mounted 
image is still busy after the copy:

Copying files to /Volumes/BitPim...

hdiutil: detach: "disk1s2" failed to unmount due to error 16 (dissenter 
-1).
Uncaught exception from user code:
         FATAL: Couldn't unmount device /dev/disk1: 4096

If I immediately attempt to manually eject the BitPim disk image icon, 
I get an error that it is busy. If I wait about a minute and manually 
do a "hdiutil detach /dev/disk1" it will unmount. As a matter of fact 
by editing buildDMG.pl to force it to sleep and retry I was able to get 
it to finish without error:

# unmount the dmg
print "> hdiutil detach $dev\n" if $debug;
$output = `hdiutil detach $dev`;
#####################################################################
## This section added by Vic Heintz to wait until not busy for detach
$sleepsecs=0;
while (($? == 4096) && ($sleepsecs < 120)) {
         sleep 5;
         $sleepsecs += 5;
         $output = `hdiutil detach $dev`;
}
print "Busy for ", $sleepsecs, " secs\n" if $debug;
## Typical busy time is 55 sec on 360 MHz G3 iBook running Jaguar
#####################################################################
die "FATAL: Error while copying files (Error: $err)\n" if $err;
die "FATAL: Couldn't unmount device $dev: $?\n" if $?;

(Typical sleep time seems to be 50-60 secs.) This is a real kludge but 
I have not yet been able to figure out what is keeping it busy. (I'm 
sure it doesn't help that this is a 360 Mhz G3.)

With this patch to  buildDMG.pl I am able to get completely through the 
Jaguar makedist without error. (Do you feel warm and fuzzy, Roger?)
