In order to get Wellenreiter v1.3 (a wireless monitoring tool) to run,
it requires GTK.pm installed. Since I no longer trust 'perl -MCPAN -e
shell' not to screw up my perl installation, I downloaded
Gtk-Perl-0.7000.tar.gz and Net-Pcap-0.04 from href="http://www.CPAN.org">CPAN and manually installed it. Note:
Net::Pcap need to be built this way: perl Makefile.PL
INC=-I/usr/include/pcap LIBS='-L/usr/lib/pcap -lpcap'
