It looks as if Easy GIF Animator (http://www.blumentals.net/egifan/index.php) might do the job - it has a free trial version, although as it's priced in US$ even registering it would be fairly cheap. As it's a PC rather than Mac app I've not had a chance to try it out but it looks like it might let you define a line along a path.
