Error in KryptOn/Magma SUnit Tests

As the first step in getting the hang of Magma, I'm trying to load  
Magma into a fresh image and run the sunit tests. So far so good with  
the loading, not so good with the tests though.

I'm getting a "MessageNotUnderstood: Rijndael  
class>>asMakoEncryptable:" in  
"MakoSecurityManager>>basicEncrypt:using:" error from the Magma tests.

I assumed it had something to do with KryptOn and ran the tests for  
it, same error. I'm probably missing some simple package somewhere,  
but have no clue which. Any ideas?

Thanks!
