Jeff,
    Just to be safe because I am going to operate on the root:
1) ls -l /usr/local/lib: libgeos-3.2.0.so
libgeos.so -> libgeos-3.2.0.so

Xianoi: I'm assuming you installed libgeos 3.2.0rc1 yourself in /usr/local, and nothing is linked against it besides your non-working basemap? If so, it should be safe to do

rm /usr/local/lib/libgeos*

shall I just remove libgeos-3.2.0.so ? But then the link for libgeos.so may not work.

2) ls /usr/local/include:
geos geos_c.h geos.h

rm /usr/local/include/geos*h

and in the folder of geos, there are a lot of files and headers.
To remove the geos3.2 headers, shall I just remove /usr/local/include/geos_c.h and /usr/local/include/geos.h ? I can not tell where the headers of geos3.1.

presumably in /usr/include. If not, you probably need to install a libgeos-dev package or somesuch.

Xianoi: Yep, there's your problem right there. My suggestion is to remove the 3.2.0 geos lib and headers from /usr/local/lib and /usr/local/include and try again.

> Xiaoni: Is there no traceback? Can you run ldd on the _geoslib.so <http://_geoslib.so> that you are actually importing when the error occurs (presumably /usr/local/lib/python2.6/dist-packages/_geoslib.so)? That will tell you what version of the geos library you actually linked. I don't think I can be of much help here - all I can suggest is that you clean out all old versions of basemap, _geoslib.so and libgeos, then rebuild again. The fact that there are so may versions floating around increases the chance that you have a version mismatch somewhere.

I have seen segfaults when there are two versions of geos installed (version 2 and version 3) and you pick up the header from one version and lib from the other version. I suggest setting the GEOS_DIR env var to /usr/local/lib and re-running the basemap install (python setup.py <http://setup.py> install), after deleting the existing build directory. Hopefully then it will grab both the header and lib for version 3.2.0 (which by the way is a pre-release, as yet untested with basemap).
