Comment(by michaelld@…):

 OK; looks like the relevant lines of debug log are:

 This looks like an infinite loop being caused by checking for "conflicts
 against"; maybe?  And, yes, it looks like muniversal is coming into play.
 Can you try building libmng without +universal & then trying qbzr again?
