It looks like you need qt-dev, or something like qt-dev.
This code will only work with qt by the way, which is wholly unnecessary for OpenGL. It's probably a bad idea in general to tie functionality that has nothing to do with a GUI into a GUI, as it will make it very hard to make the code work anywhere else. You need X and mesa and SDL; write for that and your GL code should work anywhere.
here's a better introduction I think. Took me a while to find it. SDL is nearly everywhere these days, unlike qt.

sdl::color
SDL::Color(3) User Contributed Perl Documentation SDL::Color(3)
NAME
SDL::Color - a SDL perl extension
SYNOPSIS
$color = new SDL::Color ( -r => 0xde, -g => 0xad, -b =>c0 );
$color = new SDL::Color -surface => $app, -pixel => $app->pixel($x,$y);
$color = new SDL::Color -color => SDL::NewColor(0xff,0xaa,0xdd);
DESCRIPTION
"SDL::Color" is a wrapper for display format independent color representations, with the same interface as SDL::Color.
new ( -color => )
"SDL::Color::new" with a "-color" option will construct a new object referencing the passed SDL_Color*.
new (-r => , -g => , -b => )
"SDL::Color::new" with "-r,-g,-b" options will construct both a SDL_Color structure, and the associated object with the specified vales.
new (-pixel =>, -surface =>)
"SDL::Color::new" with "-pixel,-surface" options will generate a SDL_Color* with the r,g,b values associated with the integer value passed
by "-pixel" for the given "-surface"'s format.
r ( [ red ] ), g( [ green ] ), b( [ blue ] )
"SDL::Color::r, SDL::Color::g, SDL::Color::b" are accessor methods for the red, green, and blue components respectively. The color value
can be set by passing a byte value (0-255) to each function.
pixel ( surface )
"SDL::Color::pixel" takes a "SDL::Surface" object and r,g,b values, and returns the integer representation of the closest color for the
given surface.
