PHP Fatal error: Class 'SassParser' not found - php

Question

I just installed the peroxide HAML/SASS engine for Drupal 7.x and its oxygen theme, activated and Set as default, then gave chmod -R 777 sites/all just to be sure I don't get any rwx errors.
I have the sass (ruby gem version) installed(in sass: /usr/local/bin/sass /home/danthe/.rvm/gems/ruby-2.2.1/bin/sass)
I see a blank page now, can't even login to admin panel, everything is blank(`cause of the PHP Fatal Error).
My log says

This is in my ../peroxine.engine on line 186
// Setup the Sass Parser
$options = _peroxide_get_sass_options($theme);
$parser = new SassParser($options);

Answer 1

peroxide does not rely on entirely Ruby version of SASS compiler, it's only capable of compiling with Ruby version of compiler. You have to clone the repository with the engine recursively, as it is specified in Installation guide.
Peroxide uses phamlp as SASS compiler, it is specified as Git Sub-module for the Peroxide repository.
cd sites/all/themes (or whatever your theme directory is)
mkdir engines
cd engines
git clone --recursive git://github.com/codeincarnate/peroxide.git
The error that you're having is not caused by permissions, it's a Fatal Error in php in peroxide.engine#L186
The PHP script fails to create a new instance of SassParser object, which is defined in /phamlp/blob/master/sass/SassParser.php
Please make sure that the folder is present and contains the phamlp source code. /home/danthe/public_html/AtmTopTech/sites/all/themes/engines/peroxide/phamlp
