\version "2.15.9"

{
  s1
  \tempo "Waldo"
  s1
}

The issue is that the moment after the \tempo command does not have any  
grobs where the tempo could be attached to. As soon as you change the s1 to  
a note or rest, or if you have clef/key/timesig change at the same moment  
as the \tempo, the tempo mark can be reparented. But it seems that the  
engraver misses the case that there are no other grobs at the same moment  
as the \tempo change. In that case, the tempo mark should be reparented to  
the barline...
