Subject: execle ruby process from C ?

Hello, I'm playing with a small http server written in C & Ruby CGI and 
there is something wrong

if(execle("/usr/bin/ruby", "/usr/bin/ruby" " test.rb", NULL, NULL) == -1)
{
  wlog("error execle");
  exit(EXIT_FAILURE);
}

- the C program did a chdir to the directory where test.rb can be found.
- ps ae gives
   18133 pts/5    S+     0:00 /usr/bin/ruby test.rb

test.rb contains just one line -> print "hello"

But when execle, ruby never returns... I mean, the server can be 
interrupted with a CONTROL/C and gives /usr/bin/ruby test.rb: Interrupt

I don't understand why...

I have to say that stdout and stdin are redirected to pipes - I tried 
with some unix executables like 'ls' and it works

What is the difference with ruby executable ?

Thanks
