Why use Cairo? SDL::Video can produce a beautiful red rectangle all by itself.

The segmentation fault was happening because the video mode wasn't being set right, and you were missing SDL::Rect. Here's a script that works for me: 

#!/usr/bin/perl

use strict;
no warnings;
use SDL;
use SDL::Video;
use SDL::Surface;
use SDL::Rect;

use constant WIDTH  => 400;
use constant HEIGHT => 300;

SDL::init( SDL_INIT_VIDEO );

my $screen = SDL::Video::set_video_mode( WIDTH, 
             HEIGHT, 32, SDL_SWSURFACE );

my $mcolor = SDL::Video::map_RGB($screen->format(),
                                 255, 0, 0);
SDL::Video::fill_rect($screen,
    SDL::Rect->new( 
        WIDTH / 4, HEIGHT / 4,
        WIDTH / 2, HEIGHT / 2), $mcolor);
        
SDL::Video::update_rect( $screen, 0, 0, WIDTH, HEIGHT );
sleep 10;
SDL::quit();

If that works, then you can add whatever you need to add. If you run into problems, post another question. Good luck.
