I did eventually figure a way around the problem.  Apparently when 
creating a dependency group, Anthill writes out to a temporary file 
("_temp.dependencies") to the "current working directory".  There is a 
/etc/init.d/anthill startup script that starts Tomcat as a service, and 
also runs tomcat as the user "build".  Because this service starts up on 
boot, the working directory could potentially be anywhere, but most 
likely either '/' or '/root', both of which are not writable by the user 
"build".

Why is Anthill writing this temporary file to the current directory 
instead of the location of the "anthill.home" property?  Or to "/tmp"? 
Or to "anthill.home"/projects where the dependency file is eventually 
written to?  Or even to one of Tomcat's folders?  I would consider this 
a bug.

Anyway, as a band-aid I have the startup script change to the 
"anthill.home" location, and I no longer have errors.  The startup 
script is a common startup script for Tomcat.  None of the Tomcat 
startup scripts I have seen (or even non tomcat startup scripts) ever 
forcefully change directories to make Tomcat work, as most Tomcat apps 
rely on properties to locate things, and not the current working directory.

I might suggest to one of the Anthill developers, or Anthill patch 
submitters, or some java programmer to submit a patch for this.
