The reason I've got wxsvg installed has been irretrivably lost in the
past... I haven't used dvdstyler as well, but decided to see if it is
not too hard to sort out.

It turned out it needs newer version of wxsvg than we have (it needs
at least 1.5.12, we have 1.5.3). I tried the latest - 1.5.20;
initially had some problem with libexif, which I sorted out somehow
(created the missing links in the .buildlink directry....), but later
I stuck a problem with ffmpeg:
....
