Your projection definition looks like the PCS code lookup failed.  That is
most likely due to GDAL not finding your pcs.csv file.  On Linux or Unix
this would normally live in /usr/local/share/gdal.  On windows you need
to set the GDAL_DATA environment variable to point to the directory 
containing this and other supporting GDAL data files. 

Best regards,
