This is the first thing I tried.  Identical behaviour.  Scripten is 
version 5.6 from the link on the wpkg web page.

No.  If I run wpkg for the classes of machines lab* it does what I 
expect.  (Not all of what I want, yet, but it works and installs the 
3-4 packages I've got working properly.)

 From your message this is something being spewed out by cscript, and 
not by wpkg itself.  This by itself is helpful.  Are there alternate 
js interpreters that give better debugging info?


My next step will be to remove the packages from that profile.  See if 
I can narrow it down.  I'm betting on a stupid syntax error in my xml 

On debugging.  dviPS, part of the TeX distribution has one of the best 
debugging interfaces I've run into.  With it you gave debug what 
amounted to a bit field.
debug = 1	Specials	
debug = 2	paths
debug = 4	fonts
debug = 8	pages
... and so on.
Summing them up allowed you to pick combinations.

Suppose on wpkg it was something like:
debug = 1	XML parsing  (Show parse tree?)
debug = 2	Consistency checking.  (Prints out if host file contains 
profiles that aren't in profiles, if profiles reference packages that 
aren't in packages.
debug = 4	Detailed package checking.  (Verifies the existence of 
paths, and commands)
debug = 8	Print the command about to be executed, wait for keypress, 
print exit status.
debug = 16	Put the interpreter into some form of debug mode

Now, I haven't the experience with either XML, JS, or winsnooze to say 
if any these are good ideas.  Maybe they will spark your ideas.
