matplotlib and dap.client

[Dexter Douglas]

Hello,

I am trying run the plotmap.py script found on matplotlib's web-site:
http://matplotlib.sourceforge.net/screenshots.html

I am receiving this error

[begin]
Traceback (most recent call last):
  File "plotmap.py", line 7, in <module>    from mpl_toolkits.basemap import Basemap, shiftgrid
  File "/opt/local/lib/python2.5/site-packages/mpl_toolkits/basemap/__init__.py", line 1, in <module>
    from basemap import __doc__, __version__
  File "/opt/local/lib/python2.5/site-packages/mpl_toolkits/basemap/basemap.py", line 39, in <module>
    import _geoslib, pupynere, netcdftime
  File "/opt/local/lib/python2.5/site-packages/mpl_toolkits/basemap/pupynere.py", line 37, in <module>
    from dap.client import open as open_remote
ImportError: No module named dap.client
[end]

Which port provides the dap.client module?

Thanks,
Jim
