Reported by Tom F for the autodoc process. The following (essentially) is what autodoc is doing that currently blows up:
Cause: There is code in Compiler.macroexpand() with the intention to suspend spec checking inside clojure.spec. However, it is currently doing an exact path match on SOURCE_PATH. In the load-file call above, this ends up being an absolute path.
Approach: Use the system property -Dclojure.spec.skip-macros=true to avoid encountering this issue
