The evaluation package is not part of the default packages of .LRN and that's why it doesn't come in the tarball
That's why I told you to check out the evaluation packages from the CVS. I haven't tried the apm package-loader and I don't know what could be the problem there, even though there's a bug and it has to be notified ;o)
Try checking out the evaluation packages fron the CVS and tell me if it works
