I used CPVC glue (otey gold) to glue a pvc trap together. Do I have to cut out and re-build the trap with PVC glue?

Where is this trap... if it is under a sink or Lavatory out in the open it will not hurt to leave it. Even is it does give problems later you can still replace it. If it is going to be under concrete then it might be best to change it now

I'm with letmetellu, I wouldn't say so but follow the link to see what the manufactures say.
