[systemed]

By commenting out the failing TestMapnikMap tests and test_should_instantiate in TestMapnikFeature, and changing #if MAPNIK_VERSION >= 200200 to == in _mapnik_feature_rb.cpp, it builds successfully. However, running rundemo.rb results in a very partial image, with just some of the woodland at the top left.

Curiously, reverting to 0.1.5, making the same changes, and removing the force_odd_labels code actually results in a successful build and demo image.

Same set of failures as #52 - we need to track down at what point they started failing.
