Yes, much harder ;-)

Try this at the shell: 

mkdir a
mkdir b
ln -s a S
ln -s ../b S/S
touch b/foo
ln -s S/foo foo
ln -s S/foo S/foo

Now, take a look around for a bit. And then try your chase_links on foo. 
perl -e 'my $file = shift; while(defined(my $link = readlink $file)) {
+ print "LINK: $file\n"; $file = $link; sleep 1; } print "NOT LINK: $f
+ile\n"' foo

Note the sleep in there - I did that to make it easier to kill, 'cuz it's going to go on forever.

One needs to keep careful track of current directories to figure out where the relative links are actually relative to.
