Junto: Command not found

[f201...@goa.bits-pilani.ac.in]

I was able to run bin/build update compile and got the output as:

[info] Loading project definition from /home/kathan/Desktop/junto-master/project

[info] Set current project to junto (in build file:/home/kathan/Desktop/junto-master/)

My path variables are as follows: 

export PATH="/home/kathan/anaconda2/bin:$PATH"

export PATH="$PATH:$JUNTO_DIR/bin"

export SCALA_HOME=/home/kathan/scala-2.10.4

export PATH=$SCALA_HOME/bin:$PATH

export SPARK_HOME=/home/kathan/spark-1.6.0

export PATH=$SPARK_HOME/bin:$PATH

PYTHONPATH=$SPARK_HOME/python/:$PYTHONPATH

PYTHONPATH=$SPARK_HOME/python/lib/py4j-0.9-src.zip:$PYTHONPATH

JUNTO_DIR=/home/kathan/Desktop

export PYTHONPATH

export JUNTO_DIR

but when I run junto config simple_config I get the error as "junto:command not found". what can be the possible reasons and how do I overcome them? All help is appreciated! Thanks!
