Merb can't be 'soft' frozen. That is, after installing 0.9.3 and running merb 0.9.2 on a 0.9.2 project, it still tries to load merb-core 0.9.3:
rubygems.rb:319:in `activate':
can't activate merb-core (>= 0.9.3), already activated merb-core-0.9.2] (Gem::Exception)

Jim,
What are your suggestions? Are you sure it is Merb issue and not RubyGems or your environment? Please be more verbose.

Sorry about the terse post. Lighthouse, being the lovely app that it is, lost my data when it died on update. And I was in a hurry at the time.
My suggestion is too find the cause of the problem. Gems versioning appears to be working fine, because merb-core did in fact load the requested version 0.9.2. But something somewhere tried to load 0.9.3. Nothing in my old project would do that, as the test case above tried to show.
Its pretty simple to recreate:
sudo gem uninstall merb 0.9.3
- assuming 0.9.2 is installed
merb-gen newproject
sdo gem install merb
cd newproject
merb 0.9.2

I need to have a closer look. What ORM and templating engines (or other plugins) you use?
Even if it has something to do with Merb, I doubt pre-1.0 versions will have any kind of compatibility with each other because Merb is still shaping up.

I'm using Sequel and haml.
I don't understand the compatiblity statement. The whole point of making this work is so you don't have to be compatable, and, you don't have to freeze a project before you upgrade.

Any update on this? I'm running into that same problem. Thanks.

merb-freezer rewrite is on the way: seems that nobody likes the way it works right now
