 Adding in support for zlib will allow privoxy to do more filtering.  Seems
 like a simple change to the Portfile.  Here's what I added to get it to
 work:

 {{{

 variant zlib description {Support for decompressing on the fly} {
     configure.args-append   --enable-zlib
     depends_lib-append      port:zlib
 }

 }}}
