Unable to start HDFS cluster on trunk (after the common mavenisation)

This is what I do:

In common directory:
mvn package -Pbintar -Dmaven.test.skip.exec=true
cp target/hadoop-common-0.23.0-SNAPSHOT-bin.tar.gz ~/tmp/common/

In hdfs directory:
ant veryclean binary -Dresolvers=internal
cp build/hadoop-hdfs-0.23.0-SNAPSHOT-bin.tar.gz ~/tmp/hdfs/

Untar the tarballs, and start namenode as follows:

export HADOOP_COMMON_HOME=~vinodkv/tmp/common/hadoop-common-0.23.0-SNAPSHOT-bin;
export HADOOP_CONF_DIR=~vinodkv/tmp/conf;
export HADOOP_HDFS_HOME=~vinodkv/tmp/hdfs/hadoop-hdfs-0.23.0-SNAPSHOT;
$HADOOP_COMMON_HOME/sbin/hadoop-daemon.sh start namenode

The last one simply says "Hadoop common not found." and exits.
