This one is because you need a newer version of FFMPEG (or remove the
--with-ffmpeg switch).

Error #4 (NVIZ) is a consequence of this; OGSF fails to build due to
FFMPEG issues, and NVIZ fails because OGSF is missing.

As Michael points out, (2) and (3) are because you need to use
--with-python (which requires SWIG) to build the wxPython digitising
module.
