 I installed basemap back in June but recently upgraded a number of
 outdated ports.  After doing so, I kept getting an ipython error message
 when trying to import Basemap:

 {{{
 In [1]: from mpl_toolkits.basemap import Basemap

 The problem appears to be that libgeos is now at ver. 3.3.0 but for some
 reason this _geoslib.so file in Python.framework/ is still looking for
 3.2.2, so evidently that version number is hardwired into _geoslib.so.  I
 was able to fix the problem by uninstalling basemap (which removed
 _geoslib.so) and reinstalling it, but the normal "port upgrade outdated"
 procedure wasn't able to correct this problem.  Maybe someone should look
 at how _geoslib.so is being generated during the build.

 Thanks,

 -Chris
