Interesting. Normally, when you type echo in a shell, its echo
builtin is being used (I think this applies to OS X, too).
Initially, I suspected a difference between the echo shell builtin
and /bin/echo to be the cause here, but then, on second thought, rejected
the hypothesis, as you said you were getting the correct digest
when issuing the openssl command on the command line with the same plain "echo".
In other words,
as I see things, with a plain "echo" you should be using the builtin in both
cases, i.e. from within the backticks (because of the '|' symbol, which
should cause Perl to run the command via the shell (sh -c ...)),
as well as on the interactive command line (which is a shell, anyway, typically).
So I'm still wondering what's different here on OS X. Any ideas, anyone?

What's baffling me now is that this doesn't seem to happen with Perl 5.10 on Mac OS X (as someone on this thread confirms).
