Compiling perl-gtk2 on your own 

You need the following packages from your distribution:
perl
gtk2
gcc
gtk2-devel or libgtk2.0-dev or sinilar depending on your distribution
pkgconfig

Download recent versions of the following perl modules from http://search.cpan.org:
ExtUtils::Depends http://search.cpan.org/~rmcfarla/ExtUtils-Depends-0.205/
ExtUtils::PkgConfig http://search.cpan.org/~rmcfarla/ExtUtils-PkgConfig-1.07/
Glib http://search.cpan.org/~tsch/Glib-1.081/
Gtk2 http://search.cpan.org/~tsch/Gtk2-1.081/

Extract them and run for each of them the following commands in a terminal as root:
cd <DIR>
perl Makefile.PL
make
make install

If errors arise, probably some of the required packages are missing. Feel free to contact me.
