is www/webkit-gtk2 broken?

[Alexey Dokuchaev]

hi there,

i've just noticed that www/webkit-gtk2 is apparently broken for me, per
recent tinderbox runs (locally).  i've found that the following patch [1]
fixes it.  interestingly enough, it looks like it should be noticed a
while ago, back to bison 2.6 times (we have 2.7 in the tree now).  is this
something well known or i'm just being unlucky and www/webkit-gtk2 builds
fine for the rest of the planet?
