STEP 0: If you don't have PERL, go get it and install it. Shame on you!

STEP 2: Run ZFilter once with "-C" to configure it to your default settings. Type "zfilter -C" (capital 'C'). When ZFilter asks you where it is located, tell it where you put it (ie if you put it in "/local/bin", tell it that. You may accept the default selection (what is inside the s) by pressing Enter.
