Ok, actually the system call is run under Acme::Spork.
Could it be the cause? 
use Acme::Spork;
 my $req_id =  spork( sub { system("perl mycode.pl -email \"$uemail\" 
+-type $sometype  -unit $someunit"); } )
or die qq {Could not fork for spork: $!};

I can't turn  mycode.pl into a real module. Coz in real situation it is a executable binary.
