I loaded the CryptographyPlugins package, from the Cryptography 
repository into a VMMaker image, and generated the crypto plugins 
externally. Although I have not measured it rigorously, there is a 
noticeable performance improvement with SqueakElib tests.

Untar these Ubuntu 32-bit crypto plugins into /usr/local/lib/squeak/5.0...

Let me know any issues.
