Perl and Python both work if I do 'perl h2n' or 'python hello.py'. 
Interactive mode works fine.

Sh scripts do work, as long as I remember to do ./script ;-).  I'm
running as root (but the same thing happens when I run as myself, too). 
However, this could be explained by the default behavour of exec(),
which states that if the kernel can't run a program, it execs sh and
hands it the program name in argv.
