Generally I use shellcommands for this one. Just execute your packages checks before your shellcommands in the actionsequence, so you have something like this:

control:
   actionsequence ( packages shellcommands )  # Among other things

packages:
rpm-build version=0:4.1-1 cmp=le define=true_class elsedefine=false_class

shellcommands:
   true_class::
         <comamnd>

   false_class::
         <command>

I use this to install packages, as well as to prevent the execution of some commands until after the package is installed (which takes 2 executions of the agent for the configuration to converge but I don't have a problem with that). Being the one who wrote the packages action, I could never find a way to integrate dependant commands into the action, and stopped trying because shellcommands is probably the place for them anyhow :).
