Error on executing gnu parallel command

Question

I am trying to execute a script test3.exp using gnu parallel(as follows):----

seq 1 3 | parallel test3.exp data{}/

But every time I am getting this error:---

Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at /usr/bin/parallel line 119.

I installed it using apt-get install parallel.

Output for apt-cache policy parallel perl is:---

  bhavya@guavus:/usr/bin$ apt-cache policy parallel perl

Please help me with this.

Updating the repository and then updating it using

sudo apt-get install parallel

worked for me.
