You are getting this error because queen_100 is undefined, not because 
port_profiler is missing. Furthermore, the "in module port_profiler" bit 
indicates you ealled the port_profiler from within the port_profiler 
module. If you did switch to the port_profiler module, then it is likely 
that queen_100 is not visible there.

In addition, queen_100 looks a bit strange as a goal. I assume from the 
name you are trying to run a query for an N-Queens problem. I would 
expect that a query for an N-Queens problem to specify the N as an 
argument, and probably also to have another argument for returning the 
solution, something like queen(100, Board). Do you have a predicate 
queen_100/0 in the program you are trying to run?

Cheers,

Kish
