You don't need the range lib at all, std.range provides advanced 
functions to work with ranges but ranges are a general concept. 
You need std.stdio though as this is doing file operations.

A way to do it is:

void main() {
     auto f = File("myfile");
     string buffer;

     foreach (line ; f.byLine) {
         buffer ~= line;
     }

     f.close();
     writeln(buffer);
}

Note that by default byLine doesn't keep the line terminator. See 
http://dlang.org/phobos/std_stdio.html#.File.byLine for more 
informations.
