I have used Kang's version of ps.map for Linux (non-Elf: "ps.map.linux" on
incoming at the moon) with very large vector and raster files with good
success. I have had trouble with some vector files that I had processed
through v.cutter, but not all. So perhaps the problems are related to the
structure of the vector files being used rather than the size?
