The lathe object creates a surface of revolution, so using your spline in a
lathe should do what you need.
If you want to make a radial array of copies of the actual prism object, use a
while loop. Something like:

#declare MyPrism = prism{...}
#declare Count = 0;
#declare Number = 20; //Number of copies to create
#while(Count < Number)
    object{MyPrism rotate <360 / Number * Count, 0, 0>}
    #declare Count = Count + 1;
#end
