Subject: SHA1 hash on OS X incorrect

I was just stunned by the fact that the SHA1 hash in Ruby on OS X 
(Jaguar) produces incorrect results.

I use SHA1 in the jabber4r (Ruby Jabber) library for digest 
authentication.  This effectively prevents jabber4r from working on the 
stock Ruby that ships with OS X.

test.rb...
require 'digest/sha1'
puts Digest::SHA1.new("test").hexdigest

And then a few tests:

/usr/bin/ruby -v
   ruby 1.6.7 (2002-03-01) [powerpc-darwin6.0]
/usr/bin/ruby test.rb
   94266438e06c02e522256b64ed8c833aef0270d0
    ^ ^ ^
This number is incorrect.
Under 1.6.7 on Win32 and Linux it produces the correct result.

/usr/local/bin/ruby -v
   ruby 1.8.0 (2003-01-31) [powerpc-darwin6.3]
/usr/local/bin/ruby test.rb
   a94a8fe5ccb19ba61c4c0873d391e987982fbbd3
    ^ ^ ^
This is correct.

Anyone want to corroborate?
