Thank you for the tip, I will look at it.

The following fonts related packages are installed:

(root@testjail) ~/# pkg info | grep -i font
dejavu-2.37_1                  Bitstream Vera Fonts clone with a wider 
range of characters
encodings-1.0.5,1              X.Org Encoding fonts
font-bh-ttf-1.0.3_4            X.Org Bigelow & Holmes TTF font
font-misc-ethiopic-1.0.3_4     X.Org miscellaneous Ethiopic font
font-misc-meltho-1.0.3_4       X.Org miscellaneous Meltho font
fontconfig-2.12.6,1            XML-based font configuration API for X 
Windows
freetype2-2.10.1               Free and portable TrueType font rendering 
engine
libfontenc-1.1.4               The fontenc Library

This is the code of the tested example - fetching from 
https://phantomjs.org/

(root@testjail) ~/# cat /tmp/phantom.2.js
var page = require('webpage').create();
page.onConsoleMessage = function(str) {
    console.log(str);
}
page.open('https://phantomjs.org/api/phantom/', function(status) {
    page.render('/tmp/beforeclick.png');
    console.log(page.url);

    var element = page.evaluate(function() {
       return document.querySelector('img[src = 
"https://phantomjs.org/img/phantomjs-logo.png"]');
    });
    page.sendEvent('click', element.offsetLeft, element.offsetTop, 'left');

    window.setTimeout(function () {
       console.log(page.url);
       page.render('/tmp/afterclick.png');
       phantom.exit();
    }, 5000);
    console.log('element is ' + element);
});
