gdal_rasterize (http://www.gdal.org/gdal_rasterize.html) is worth a  
look. It is the only way I have found to do raster clips using a  
vector. It will not trim or crop the actual raster, so you likely want  
to reduce the raster to a rectangle that covers the coordinates of  
interest. You can use gdal_translate with the -projwin option, or use  
gdalwarp with the -te option.

Example crop:
gdal_rasterize -b 1 -b 2 -b 3 -burn 255 -l shapefile_layer_name -i  
shapefile.shp raster_file.tif

Regards,
John
