Hi Dietmar.

A good error report would answer the following questions:

* What is the output you get? What is the output you expected?
* What error messages do you get?
* What is the minimal script that reproduces the error? (e.g. does
'parallel echo ::: 1 2 3' also not work in the script?)
* What version of parallel do you run?
* If you suspect the error is dependent on your environment, can you
reproduce the error on one of these VirtualBox images:
http://sourceforge.net/projects/virtualboximage/files/

This is described in the man page (in the section REPORTING BUGS).

With decent error reports you are more likely to get a useful answer.

Exporting should only be needed if you call functions from GNU
Parallel, and your example does not do that.
