It seems that the default agg polygon clipper is not reliable when it is used for geometry output, as stated on their site. I tried to figure out what might cause the broken polygons when using this backend in VectorTileMap and found that the clipping messes things up. I've hacked Clipper into polygon processing and it seems to do the job well. the results is in my 'origin' branch. maybe you can integrate it properly :)

do you have a guess what might cause this error? node-mapnik tests ran successfully. I've added 'ldflags': ['-zdefs'], to bindings.gyp target and it shows that
vector_server.cpp:(.text+0xdf): undefined reference to `Map::constructor'
(besides everything else also being undefined references). I'm building on ubuntu 10.04 with default nodejs 0.8 and mapnik master

Just in case you didnt saw it already: https://github.com/jeffdameth/TileStache/blob/master/TileStache/OSciMap/TileData.proto contains the protocol definition.
From looking at the code I was wondering why you implemented the parser analog to oscim MapDatabase instead of using the pbf code generator. Needles to say that I'm thrilled that you write a implementation for mapnik which was also somewhere on my want-todo list :)

The 0.2 protocol is still inofficial (i.e. not enabled in the apk) if you have suggestions for improvement please let me know. One thing I would like to change is instead of having a fixed list of keys and common tags to transmit them with tile 0/0/0 for each map.

When I use "npm install", it have a bug during building vector_server.o

Please help me fix this bug. Thanks so much!
