You mean "How do I do this in perl?"

Use readlink().

Create the symlink in your user's path. In your perl code, add
logic to read the symlink with readlink() and then strip off
everything accept the base path. As a bonus, grab your present
working directory with $ENV{PWD}. Now you have variables that
tell you about both directory trees that you need access to, and
can use chdir() at will.
