Should not be difficult... although there's not much info about it...
let me try giving you a brief explanation... the idea is that you can
create a class that's a subclass of PyDevBuilderVisitor and override
the needed methods (in your case, probably only
visitChangedResource)... and register it as such:

<extension point="org.python.pydev.pydev_builder">
    <builder_participant class="my.pydev.BuilderClass"/>
</extension>


and you also want to give it a priority higher than code-completion
(so that it's built after it, as you want may want the code-completion
caches built already):

    @Override
    protected int getPriority() {
    	return PyCodeCompletionVisitor.PRIORITY_CODE_COMPLETION+1; //just
after the code-completion priority
    }

in the visitChangedResource you can do something as:

if(module == null){
    module = getSourceModule(resource, document, nature);
}

module.getAst() --> returns the visitor structure you want to traverse..

And then just create the markers (regular eclipse markers) and add
them to the resource being visited.

Cheers,

Fabio

p.s. I'm putting pydev-code in the cc (those questions really belong there)
