From personal experience (and others') you get some odd error messages
when you start mixing different versions of libgdal. I would expect the
error to go away if you stick to one version of libgdal. Ubuntu-GIS
should have all the packages you need without having to mix GDAL versions.

You can also loop through the features with relatively simple Python

Not sure if this would be straightforward in GDAL but you might want to
consider a combination of GDAL + Shapely

With gdal_translate you can do per band re-scaling. I've used it on

Are you sure that the white you see is a pure 255/255/255? Albeit, the

Both input datasets (mask and raster) exist, which is why 1. works.
Option 1 doesn't use any of version 1.8.0 flags, which is why I thought
