If it's a symlink you should be able to readlink it (see perlfunc) to get
the thing that it points at
(although you'll have to do some file concatenation logic based on whether
it's absolute or relative)
And then you can test that (and work your way along the symlink chain,
but make sure you put a trap in after a some large number of steps else
you will be gotcha'd by symlinks looping back to themselves)
