INSTALLATION ======================================================================== You will need Perl (5.10 or higher), a C compiler and some Perl modules. You can try to configure the tool before installing the modules, or install them previously. To try to configure the tool, and check for the modules existence type: ./configure Perl modules installation should be straightforward. Probably the only detail to be mentioned is that you should install Term::ReadLine::Gnu and not Term::ReadLine. You can get all these modules from CPAN (http://www.cpan.org). After configuring the tool successfully (running ./configure without warnings and/or errors) you need to compile the tool: make and then, test it: make check and, normally as root, install it: make install After installation you might have problems if your Linux is not aware of the installation path from NATools. For example, if you installed under /usr/local, then you should add /usr/local/lib to the /etc/ld.so.conf file, and run ldconfig (both as administrator). ========================================================================
