How to exclude apps when building Haiku?

Well, if you had provided us with pictures of KDL we could at least try to guess what’s going on but now that you’ve started over we won’t be able to understand the problem and fix this. Oh, well.

Again, saying that “you can’t” something isn’t helpful at all. Let me quote @extrowerk here:

You can improve you chances to get a useful help/hint with providing all the information in one post, without requiring us to ask you about possibly-important details like “And what was the error message?”.

How difficult can it be?
