Ok, I see the same error message. However, I'm not sure it's V2 bug. Consider 

help-project/app3/main/Jamfile

and

help-project/app4/main/Jamfile

Both declare exe called app1 and stage them into ../../bin -- i.e. to binaries 
with the same name are staged to the same location, thereby causing the 
error.

I suspect that the original error you had was for another reason. I've just 
comitted the attached patch, which makes the error message unconditional but 
also fixes a typo which causes locations for targets to be always reported as 
same. Could you try rerunning your original testcase?
