Looking in wrong directory for .less files.

Live CSS is working perfectly for normal css files. However, when I enable support for less files, and add a global.less file in my theme.info file, the live_css path to the file seems to get confused.

Path to css files looks like this....
http://mydomain.com/drupalbase/sites/all/themes/mytheme/css/main.css
WORKING

But less is looking for...
http://mydomain.com/sites/all/themes/mytheme/css/global.less

It is skipping the "drupalbase" sub directory of my drupal install.

I think line 204 of live_css.module is the problem...

$path = $_SERVER['DOCUMENT_ROOT'] . '/' . $path;

Do we need to use drupal_base() instead of DOCUMENT_ROOT ? We just need a way of picking up sub directories.

I guess it's because .less files get treated as external files....

  if (drupal_substr($input_file, -5) == '.less') {
      $styles['#items'][$key]['type'] = 'external';
    }

And my dir structure does not represent the external address.... for example.

Local path = ~/myhome/drupal/drupalbase/sites/all/themes/css

/var/www/drupalbase = Symbolic link to drupalbase dir above

External Path = i.p.address/drupalbase/index.php

Perhaps my set up is a bit unusual, but this is quite common on local development installs too.
It would be nice if this great module worked for all directory set ups.

If it can't be fixed, perhaps just add a comment in the LESS setting to say that .less files will only work if drupal is the basedir of the document root url.
