Spruious error: undefined variable about jsunpack-n HOT 3 CLOSED

[deleted comment]

(Deleted that last comment.)  The error disappears if I delete (comment out) 
the line that reads:  asyncTracker = new Tracker();

I'll try to get spidermonkey built on my dev box tonight.

These error messages are to be expected in normal jsunpack output. The goal of 
the error being displayed is showing whenever jsunpack is unaware of some 
variable. In the future if you add a definition for hostName in pre.js, you 
might have better luck decoding something that requires it.
