In fact, on a machine with the right php installation (ie including 
imagemagick I think) and a copy of libgabor.php, the following code is 
all you need to generate your own gabor sets. Adjust parameters as 
required:

<?php

// libgabor.php can be found at
// https://github.com/smathot/gabor-patch-generator/blob/master/src/
libgabor.php
require("libgabor.php");

/**
    This wrapper defines the constant values to pass to the 
    generate_gabor function defined in libgabor.php.
    The variable values are handled in the for loops below.
**/
function make_gabor($orient, $freq, $outfile) {

    // The size of the patch in pixels.
    $size = 96;

    // The envelope, gaussian, linear, hann, hamming, circle,
    // or rectangle.
    $env = "gaussian";

    // The standard deviation of the envelope, in case it is
    // gaussian.
    $std = 12;

    // The phase of the patch.
    $phase = 0.0;

    // The background color as an RGB array.
    $color0 = array(128, 128, 128);

    // The first foreground color as an RGB array.
    $color1 = array(255, 255, 255);

    // The second foreground color as an RGB array.
    $color2 = array(0, 0, 0);

    generate_gabor($orient, $size, $env, $std, $freq, $phase,
                   $color0, $color1, $color2, $outfile);
}

for ($o = 30; $o < 61; $o += 5) // $orient values 30 .. 60
    for ($f = 0.2; $f < 0.9 $f += 0.2) { // $freq values 0.2 .. 0.8
        $fn = printf("gabor_patches/patch_%02d_%02d.png", $o, $f * 10);
        make_gabor($o, $f, $fn);
        }

You may need to create the subdir gabor_patches to save files in before 
running the program.
