In MacPorts, there are six output "levels": error, warn, msg, notice, info, debug. Each piece of code that wishes to produce output decides the appropriate level for each line of output. The main.log contains all output, in a similar but different format to that which you get if you use the debug flag (-d). The verbose flag (-v) gives you less output than debug, and normal mode (no flag) gives you less output than that.
