Trying to set defaultroute to a $(variable)

[Chip Seraphine]

I have a module that consults an administrative database and sets the 
variable $(dfltrt) to the IP address of the correct gateway for that 
host.  So far, so good.

However, the problem I am seeing is that no matter what I try with the 
actionsequence or imports, cfengine (2.0.6) always wants to hit the 
"defaultroute" section before the variable is set by the module.  I've 
tried numerous permutations of importing chains and running the module 
at various points along it, but it seems like this is just unavoidable.

The funny part is, I seem to recall getting this to work once before 
when I was testing this, but I can no longer reproduce that.

Basically, it looks like this:

control:
        AddInstallable = ( found_dfltrt )
        actionsequence = ( "module:get_dfltrt" shellcommands netconfig )

defaultroute:
        found_dfltrt::
                $(dfltrt)

shellcommands:
        "/bin/echo got dfltrt $(dfltrt)


Obviously, the reality is a bit trickier, but this is the gist. 
Removing the 'found_dfltrt::' line results in a syntax error as the 
unexpanded variable $(dfltrt) is not valid.

The module spits out this output:

+found_dfltrt
=dfltrt=10.10.1.1

The echo statement in shellcommands prints the correct value of the 
variable just fine.

If I hardcode $(dflrt) in the control: section, things work fine.  This 
problem only occurs if I set it via module.

Any suggestions would be greatly appreciated!
