I think Bernard had the better solution --- the above presumes that
filenames won't ever have parens in them.  (Which, admittedly, is a
bad idea under most Unix shells --- but that doesn't mean we should
perpetuate the problem.)  Also, I'd rather see us keep the platform-
dependent ".so" extension at the end of its string, where it's easy
to spot and fix when needed.
