You have changed something in the aodv module? In particular, have you changed THE aodv module and copied something you found online from someone else which was developed in an order ns-3 released?

The fact that it has the same name (aodv) does not mean it is the same module. You should read the manual on how you add a new module in NS-3 here 
http://www.nsnam.org/docs/manual/html/new-modules.html

The problem is the wscript file and the structure you use. It has been changed and in particular your error is here

headers = bld.new_task_gen(features=['ns3header'])
