s3cmd not "Getting" the distcp jar file
===

Hi guys : I'm trying to get the s3 distcp jar file via s3, in an EMR cluster : 

s3cmd get s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.1/s3distcp.jar

However, its not working.  I've tried running s3cmd ls :

    hadoop@ip-10-58-254-82:/mnt$ s3cmd ls s3://eu-west-1.elasticmapreduce/libs/s3distcp/
    Bucket 'eu-west-1.elasticmapreduce':
    2012-06-01 00:32   3614287   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.1/s3distcp.jar
    2012-06-05 17:14   3615026   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.2/s3distcp.jar
    2012-06-12 20:52   1893078   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.3/s3distcp.jar
    2012-06-20 01:17   1893140   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.4/s3distcp.jar
    2012-06-27 21:27   1893846   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.5/s3distcp.jar
    2012-03-15 21:21   3613175   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0/s3distcp.jar
    2012-06-27 21:27   1893846   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.latest/s3distcp.jar


And it seems to confirm that, in fact the file exists.  

Is there a simpler methodology for accomplishing this?  I have been told that this might be related to privileges (but I can't imagine that s3 would put restrictions on getting the s3disctcp jar file).
