I can't say I know much about JNI but I've used some libraries like
SQLiteJDBC and Qt Jambi which bundle the native libraries in the jar, so
the consumer of the library can use them just as if they were normal
java libraries, which is very convenient. Looking at the source code to
SQLiteJDBC it looks like what they do is check the platform with
(System/getPropertly "os.name") and then copy the appropriate lib files
(extracted from the jar with getResourceAsStream) to /tmp (just using
java.io.File/createTempFile) and then call System/load on them.

I'm a little unclear about what are you proposing "lein run" would
actually do for JNI stuff. Something like this?
java -cp 'src:classes:lib/*' -Djava.library.path=native-lib/ \
clojure.main -i src/gears.clj -e "(gears/-main)"
What would it set java.library.path to? Or are suggesting that would be
configurable in the project.clj?
Cheers,
Alex
