It runs properly from the command line.

I assumed that if backtick and opening a pipe fail, system will 
undoubtedly fail, too.  Yup -- I just tried it.  

Actually, in today's test, all three variants (backtick, pipe, system) 
fail without setting $? nonzero!  And yet, the very same command, 
from the command line, works.

>what version of perl are you using?

I think I'm using ActivePerl version 5.20.  perl -v reports binary build 
522, from 11/99.

Of course.

Yes, though it doesn't seem to matter whether I explicitly name the 
executable or fetch it via PATH.
