Hi,
I've uploaded a new version of spatial-trees to cclan, with two fixes:
* conditionalize (on #+slow :-) the code checking that all the coordinates are in the right order in MAKE-RECTANGLE
* make spatial-tree-viz a static-file, so that if a user installs spatial-trees systemwide and then someone else installs clim, you don't get write errors.
Cheers,
Christophe
