how to install Spiderzilla for GNU/Linux or other *nix systems like fedora ubuntu

Spiderzilla for GNU/Linux (or other *nix systems)
This version is working only when you have xfree and HTTrack packages installed.
Why Xfree? Because Spiderzilla is using xterm.
After that you can install HTTrack from sources from this address httrack-3.33.tar.gz.
To install HTTrack here are the command lines:
$ tar xvfz httrack-*.tar.gz
$ cd httrack-*
$ ./configure --prefix=/usr/local && make
# make install (root permissions required to install HTTrack)
$ /usr/local/bin/httrack
