ant build problem

[wpf5511]

 I use the ant build command to build the RHive from source.

BUILD FAILED
/home/wpf/RHive/build.xml:39: /home/wpf/RHive/${env.HIVE_HOME}/lib does not exist
I see the build.xml that line is 

<path id="classpath">
    <fileset dir="./" includes="**/*.jar"/>
    <fileset dir="${lib.dir}" includes="*.jar"/>
    <fileset dir="${env.HIVE_HOME}/lib/" includes="**/*.jar"/>
    <fileset dir="${env.HADOOP_HOME}" includes="**/*.jar"/>
</path>
my os is ubuntu 14.04,and i set the HADOOP_HOME and HIVE_HOME in /etc/profile ,my hadoop version is 2.6.0 and hive version is 0.14
