I spent some time trying to get Iceberg version dev-0.5 to load properly (yesterday's script is not working).
The reason is that
Metacello fails to upgrade packages from a baseline. And there is no way (at least
that I found) to force the upload.
So this is the updated script to test dev-0.5:
1. Download latest vm and image.
2. Execute this on your image
This should actually remove old iceberg version then install new one.
