So I obtained todays svn snapshot of Stage 3. I tried to compile it, but 
it failed near the end. Small change in code solved the problem:

(I'm putting it here as I have a feeling that patch tracker is ignored 
nowadays).
After 'make install' was completed, I ran to /usr/share/stage directory to 
find worlds files. Unfortunately, all I found was directory called 
'assets'. No *.worlds files inside of it. Then I went into sources 
directory and found worlds directory there. I tried simple.cfg with player 
and it works fine (as in Stage-2.x), I have a feeling that it works even 
faster and more reliable on my quite old desktop PC than Stage-2.1 that I 
was using so far. Robot did not move until I connected with playerv, which 
I guess was expected behaviour (how 'ctrl "wander"' corresponds with 
that?!). No other world wanted to work with Player (missing interfaces 
definitions?). So I tried standalone stage simulator with everything.world 
- looks nice, hovever, I guess I need to configure standalone controller 
for all those robots to make them move (how?).
