Head has too many changes that I don't want to try to adapt to at the
moment (compilation failed with all sorts of errors). So next I tried
version 0.5.5 -- and it worked without any linking error! [1]
Unfortunately, the 0.5 branch was started in 2009, so it may be that
the code that causes the linking error simply hasn't appeared in that
branch. Still, it's progress!
