Hi Bob

> DOES NOT appear under the meta folder

I don't use AutoWeka, but I could install 2.6.3 without problems and
the AutoWekaClassifier shows up (in the meta section).
However, it doesn't run on my Linux machine (I've attached the error message).
Not sure who's maintaining that package nowadays.

Cheers, Peter
