Hey Mikel,
0.6.1 is pretty much trunk, so Jon's fix should be included.
Seems like generally a problem with Mapnik's png256 format when used
with styles like you have. png256 is the default format used in
renderd, so you'd just recompile renderd after changing that from
"png256" --> "png":

Yes, it's 0.6.1
As Chris suggested, is it possible to adjust the color map size
without recompiling mapnik?
If not, I'll svn up and recompile everything, but would rather try
to avoid that right now :)

If it only effects PNG files with 16 colormap entries then this
could be
the fix:
$ svn log include/mapnik/png_io.hpp | more

Fix reduce_4() to make it consistent with reduce_8(). This was
breaking
tiles which were compressing down to a 16 entry colormap. All the
pixels
were being set to the alpha index.
