I need to use Rtrees to make some code I'm running faster. However, in order to use Rtree, I need to install libspatialindex. When I've installed packages in the past I've been able to either download a .exe file from Chris Gohlke's site, or use
setup.py install from the command prompt, after extracting the contents of a tar.gz file.
The problem I'm having is that 1.) There is no .exe file on Gohlke's site, and 2.) After downloading 'spatialindex-src-1.8.4.tar', and trying to extract it, I get the error 'Can not create output directory' - I have no idea what that's all about. 3.) I go to http://download.osgeo.org/libspatialindex/ and download the appropriate file - i.e. libspatialindex-1.8.1-win-msvc-2010-x64-x32.zip, when I unzip it seems obvious that everything I need is there - there are a number of .dll files. It seems like this last one is the best route, but after unzipping, I don't know what to do with all the files. Do they need to do into my DLLs folder?
