I should note that this failure is under Cog. I am trying to build plugins
for Windows Squeak 4.0.2, but am having problems - the topic of a different
thread I started.
Some DES test fail. In CryptoDESTest, I am failing on #testDES, #testDES2,
#testDESFormal, and #testTripleDES, with the DESPlugin loaded. Without the
Plugin all pass green.
