you can explicitly extract both those DLLs from the GAC(Global Assembly Cache), and then make sure they are in your bin folder with the executable you are calling.

in that way, your references are available, without having to install SQL on the machine it is executed from.

the problem, of course, is you need someone to select the target server with the appropriate permissions., and split the document up into multiple separate commands based on the GO statement, and execute each of those commands in a loop.
