I'm not really sure why this would happen?

I don't think so - when you build from source, all the plugins (and the broker) should pick up the same VERSION as each other. If you're not building from source, I'm not sure which constraint you're running into. What are the symptoms (i.e., what goes wrong)?

The instructions in the README now specify that you should check out the git repository into a folder called 'lager' (regardless of the actual source repository name), the APPNAME variable has been reset to 'lager' and I've renamed the uploaded binary to 'lager-2.0.0.ez' - this should fix these issues for you. In the long term, if enough people really want to use lager then we'll probably come up with another (better) approach than this, but I just wanted to get folks going for the time being so we can get some feedback.

If you're building from source then do a `make clean` in the umbrella before attempting a rebuild (with the renamed rabbitmq-lager => lager directory freshly checked out) otherwise the build system will get all in a twizzy about dependencies.

I did this because it wouldn't build from source for me (see previous post), but that's probably because I just cloned Tim's repo into a subdir without renaming it. Having said that, I was just doing this quickly between flights, so I didn't really look into it too deeply.
