Use 'raco exe' to compile into executable code.

Run 'raco help exe' for more documentation.

What you did--as far as I can tell--was to *run* the file.  There are several reasons it could then have been waiting.  One is that the file requires planet libraries that were compiling.  Another, simpler one is that the file you're running may parse input from stdin, in which case it was waiting for you to provide input.

Finally, I'm a little surprised that you want to compile the file; usually, compiling like this is useful only to create a stand-alone executable that you can share with other people.  In other circumstances, it's simpler (and, I believe, generally about as fast) to leave the file in bytecode format.
