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.

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