Evan: I think this is a LD_LIBRARY_PATH problem. There are two
possible workarounds:
1) set the LD_LIBRARY_PATH environment variable to include
/usr/local/lib, i.e.
export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
2) edit setup.py and make the following change
currents_nbp:(basemap_svn)$ svn diff
Index: setup.py
===================================================================
--- setup.py (revision 4791)
+++ setup.py (working copy)

extensions.append(Extension("matplotlib.toolkits.basemap._geod",deps+['src/_geod.c'],include_dirs

# for some reason, pickling won't work if this extension is installed
# as "matplotlib.toolkits.basemap._geos"
-extensions.append(Extension("_geos",['src/_geos.c'],library_dirs=geos_library_dirs,include_dirs=geos_include_dirs,libraries=['geos_c','geos']))
+extensions.append(Extension("_geos",['src/_geos.c'],
+ library_dirs=geos_library_dirs,
+ runtime_library_dirs=geos_library_dirs,
+ include_dirs=geos_include_dirs,
+ libraries=['geos_c','geos']))
then rebuild. As Eric Firing pointed out to me, adding
runtime_library_dirs negates the need to set LD_LIBRARY_PATH manually.
This is already done in svn, and so 0.9.9 will not require manually
setting LD_LIBRARY_PATH.
HTH,
