Sorry if this is a double post; used the wrong email in the first reply and
got at least one failure notice...
This is terminal IPython and IPython Notebook. (I noticed it first in the
IPython Notebook). The backends are the same in both Python and IPython
(and IPython Notebook). I have not changed any of the default IPython
settings.
I'm wondering if this is a path issue of some sorts…namely IPython is
picking up an old version of geos that I cannot seem to find. At least this
is the angle I'm currently trying to work on. I should add that I've remove
all my manually installed modules and "started over". I built Numpy,
Matplotlib, Basemap, and then IPython (in that order), and still have the
same segfault issue.
