I just noticed something. This might not produce the effect you want;
a symlink aims at a specific named target, and if you use a relative
path, it's relative to the directory containing the symlink, not the
directory you were in when you created it. What happens if, instead,
you do this:

% cd cgi-bin
% ln -s ../test.py .

? Conversely, can you, with whichever setup you're looking at, read
the source code for the script by catting it from cgi-bin? It might be
that the link is actually unreadable or pointing to the wrong place.
