'sterea' should be okay I think, it stands for OBLIQUE_STEREOGRAPHIC as far
as I know.

What surprises me is that my transform is running ok under linux but fails
under win.
It seems that somewhere a lookup for this projection is missing.
If someone can tell me the easiest way to produce some version numbers that
might help.

Below I'll put my code that produces the error (at the point where
'point.Transform(coordTrans)' should happen from epsg=28992 to epsg=4326)


from osgeo import ogr, osr

def transf(sample,epsgIn,epsgOut):

    # CREATE PROJECTION OBJECTS
    srIn = osr.SpatialReference ()
    srIn.ImportFromEPSG(epsgIn)
    srOut = osr.SpatialReference()
    srOut.ImportFromEPSG(epsgOut)
    coordTrans = osr.CoordinateTransformation(srIn, srOut)
    
    # CREATE OGR POINT OBJECT, ASSIGN PROJECTION, REPROJECT
    x = sample[0]
    y = sample[1]
    wkt = 'POINT(%s %s)' % (x, y)
    point = ogr.CreateGeometryFromWkt(wkt)
    point.AssignSpatialReference(srIn)
    #point.TransformTo(srOut)
    point.Transform(coordTrans)

    print '======================='
    print 'Input: ',wkt
    print srIn.ExportToProj4()
    print 'Output1: ',point


# CREATE WKT STRING OF POINT COORDS
sample = (' 776041.000', ' 3386618.000')
transf(sample,26916,4326)
sample = (' 143423.00', ' 473057.00')
transf(sample,28992,4326)


Output:
