[Alexandre DERUMIER]

Oh, yes, you are right

root at kvmtest1:~# ls -lah /bin/sh
lrwxrwxrwx 1 root root 4 Mar 21  2012 /bin/sh -> dash


#echo "dash    dash/sh boolean false" | debconf-set-selections ; dpkg-reconfigure --frontend=noninteractive dash


root at kvmtest1:~# ls -lah /bin/sh
lrwxrwxrwx 1 root root 4 Oct 29 10:35 /bin/sh -> bash

This is due to the fact that debian uses dash as /bin/sh default since 
squeeze and dash does not support pipefail. That's why i mapped /bin/sh 
to bash again on all of my debian systems. 

Another idea could be: 

system( "bash", "-c", @args ); 

Another idea you can try is set the shell via: 
$ENV{SHELL}
