It appears that the non-tiled OSM "cloudemade_998" option uses map
caching, and it works fine with libdb5.1 in Ubuntu 12.10.  After
downloading, the "map cached" message appears in the lower left.  If I
arrow key over to a previously used section of the map, it indicates
that I am using a cached map.  Also if I check the files in
~/.xastir/map_cache, the modified dates are not updated when I use
what is indicated as a cached map.  The files in the
~/.xastir/map_cache directory are definitely snapshots of the
cloudmade maps that are in use.
