I'm sending this response to squeak-dev as well, as that is the more
appropriate place ...
Cog works well with trunk images; you need to have the latest updates
in there, though. If I understand your message correctly, you seem to
be unable to update to the latest trunk, right? Have you set the
update site to http://source.squeak.org/trunk in the preferences
Once all the updates are in, Cog starts up my trunk image, and I'm
enjoying the speedup. :-)
Pre-built releases take time to prepare, and please bear in mind that
Cog was released just some few days ago. Also, Cog does have its
glitches (I experience some difficulties with bytecode simulation, but
also with stepping in the debugger - report upcoming) and is probably
not 100 % stable for all purposes that the non-Cog VMs were well
To summarise, while Cog is the "latest and greatest", as you put it,
it should be considered beta. The stable Squeak release is 4.1 plus
the latest VM, and in my actually not so humble opinion it is
completely sufficient to provide pre-built releases for *that*.
Perhaps I misunderstood you here and there: apologies for that, then.
