You need the builders as soon as you want more than simple parse-error 
reporting. Especially things like quickopen, outline, classbrowser, ... 
require declarations in the DUChain. And imo, if you already have a parser, 
adding the builders should be a piece of cake :) Please push your code to 
playground/devtools/kdevelop4-extra-plugins so we/I can have a look at it.

Please remove the indentation changes from the patch, this way I cannot really 
review the changes.
