I'm trying to read in the state boundary shapefile from 
http://nationalatlas.gov.  However, the Aleutian Islands
cross the 180th parrallel, so longitude goes from +180 to -180 at that 
point.  I end up with the end of the
Aleutian Islands getting disconnected.  What is the solution?  I used 
v.in.ogr and set up a location using the information that came
with the shapefile.  See spatial information below..

      Latitude_Resolution: 0.000278
      Longitude_Resolution: 0.000278
      Geographic_Coordinate_Units: Decimal degrees
      Horizontal_Datum_Name: North American Datum of 1983
      Ellipsoid_Name: GRS1980
      Semi-major_Axis: 6378137
      Denominator_of_Flattening_Ratio: 298.257222
