Was the problem you're having occurring with the latest version of cc.logging (the one that uses eval)?
The logging macros do not emit calls to the logging implementation, but rather to c.c.logging functions that are implemented at runtime via eval. As such, the latest code should always pick an implementation based on the runtime classpath, thus the environment in which AOT compilation takes place should have no effect. While I'm not sure how it could happen, this may end up being a classloader problem.
