Generally there's never any guarantee that functions with one
distribution will work with another, since in all "production"
installations this isn't an issue as $fpath is set appropriately.

However, I think the following should work in both versions and I'd be
interested to hear about it going wrong...  In fact I'm not sure why the
code uses ":gs" instead off "//" which is a more obvious operator at
this point.  Possibly the latter used to be flakey.
