python 2.5
Matplotlib 1.0.0
basemap 1.0
pygrib 1.7
pyproj 1.8.6
numpy 1.4.1
Latest source of GRIB API
Jasper 1.9

At this point I am trying anything. I upgraded everything to the latest version. I now receive the following error, and a warnings.

/usr/lib/python2.5/site-packages/matplotlib/contour.py:474: DeprecationWarning: PyArray_FromDims: use PyArray_SimpleNew.
  nchunk = self.nchunk)
/usr/lib/python2.5/site-packages/matplotlib/contour.py:474: DeprecationWarning: PyArray_FromDimsAndDataAndDescr: use PyArray_NewFromDescr.
  nchunk = self.nchunk)

Traceback (most recent call last):
  File "testImageGen.py", line 124, in <module>
    m.drawmapboundary(linewidth=0.0, color=[15./255., 53./255.,73./255.]) 
  File "/usr/lib/python2.5/site-packages/mpl_toolkits/basemap/__init__.py", line 1325, in drawmapboundary
    for spine in ax.spines.itervalues():
AttributeError: 'AxesSubplot' object has no attribute 'spines''


Here are the functions I am calling and their associated errors.

bmap.drawcoastlines(color=[15./255., 53./255.,73./255.], linewidth=0.15)
bmap.drawcountries(color='k', linewidth=0.25)
bmap.fillcontinents(color="white",lake_color=[51./255., 153./255.,204./255.])
bmap.drawstates(color='k', linewidth=0.25)

No errors for the above calls

bmap.drawmapboundary(linewidth=0.0, color=[15./255., 53./255.,73./255.]) 

I receive the AxesSubplot error listed above. 

I believe the errors before (and possible the current) were due to operator error. I should have started with the latest version of the source from the start rather then installing deb packages. 


Thanks,
