Hi all,<br><br>A quick and a dumb question: I've been trying to get the ruby port working in order to compare the api query from it with the results of our C++ implementation of the api. I've imported a uk sub-section of world using planetosm-to-db.pl into a mysql db - it seems to be successfully populated. The local version of the server is up and running and in development mode. However I get errors from the ruby when attempting to use the map query. Can anyone help - or tell me which M to RTF? The error follows:<br>
