OSError: libspatialindex_c.so.5: cannot open shared object file

I'm getting the following error. Any ideas?

Traceback (most recent call last):

That seems like an issue with the python environment. Try printing os.environ right before the exception to see if it has the correct environment. It could be that the rtree library isn't being correctly detected. You could try rebooting or doing sudo ldconfig on linux.
