Subject: distributing ruby with Rubyscript2exe - and a path problem ?

Dear all, 
I am trying to put together an executable file from 
a  ruby script containing an external application (gnuplot), 
on machines that  doesn't have Ruby nor gnuplot installed, 
using the way this is described in  
_http://www.erikveen.dds.nl/distributingrubyapplications/index.html_ 
(http://www.erikveen.dds.nl/distributingrubyapplications/index.html)   
_http://www.erikveen.dds.nl/tar2rubyscript/index.html_ (http://www.erikveen
.dds.nl/tar2rubyscript/index.html)   
_http://www.erikveen.dds.nl/rubyscript2exe/index.html_ 
(http://www.erikveen.dds.nl/rubyscript2exe/index.html)   . 

I have made a directory 
/temp5, 
put in it my application  init.rb, 
which writes some data into a file, saves it, and then 
calls  gnuplot via the system command to show a plot 
using the commands in that  file. 
This works fine on the machine I am creating 
the executable on,  
but when I test my application on an external machine, 
where there is  neither gnuplot nor Ruby installed, it just starts 
and ends without doing  anything - no file is written, 
no gnuplot is started, no error message is  given. 
What am I doing wrong ? Is there some problem 
configuring some  paths? The executable file is quite 
large (~8MB), and it seems to contain  what's necessary 
from gnuplot, as far as I can tell (see below). 
Below  is what I get from the eee-list and the tar-list commands 
on the machine  without Ruby and Gnuplot installed. 
 
$ ./temp5_linux --eee-list
 

Thank you very much for your help. 
Best regards, 
Axel
