Volker is correct. The reason you will break your system is that you do not have enough knowledge to know what to put back, and you don't know how to read the error messages and know what they mean. Here's what portage does NOT do: Tell you that flag x is missing and this will cause issues a, b and c, then give you exact instructions how to make it better. Here's what portage DOES do: Give you some weird error message with the word "backtrack" in it, or messages like "no parents that could not be satisfied by other packages in slot" or something about blockers in flashing red blink text, or it might even just say nothing giving the impression everything succeeded. And then your computer explodes.
