I just updated the OpenBoundClasses JSFL. This update should work smoothly on a mac (was tested, but not thoroughly), this version should support just about any path you feed it.
This version supports an array of classpaths (similiar to the IDE), you can setup the array exactly like you have yer paths set in the IDE and everything should work as expected. This will require a minor edit to the .jsfl file.
You can download the file from here and again if you have any issues, comments, or suggestions please leave a comment.
