Hi Ralph,

I would recommend getting your image and VM through the references on
http://www.squeak.org/Downloads. In particular, please get your VM through
one of those links, rather than relying on apt-get. The Debian package may
work, but problems have been reported particularly for 64-bit systems.

Given your objective to move from 3.11 to 4.5, the official 4.5 release
is a good image to work with. Be aware that a new release is pending. This
will be 4.6/5.0, with the 5.0 designation applied to a new object memory
format (by Eliot Miranda) that will support better performance and new
garbage collection strategies. But you can very easily move your application
from 4.5 to the newest 4.6/5.0 once you have in running on 4.5.

The Cog VMs (mirandabanda.org) will give you superior performance, and the
traditional interpreter VMs (squeakvm.org)) will work well with both Squeak
4.5 and your current 3.11 images.  Any of these VMs will serve you well,
but please do get one through the links at http://www.squeak.org/Downloads.

HTH,
Dave
