Missing src/Transform/Format/template.html

[lokeb]

I am using the PHP version 7 fork, and downloaded the bin/box/mondrian.phar. On executing
mondrian.phar d --ignore=tests --ignore=vendor --format=html project-dir, I get the following warning, and the generated html is blank.

PHP Warning: file_get_contents(phar:///mondrian.phar/src/Transform/Format/template.html): failed to open stream: phar error: "src/Transform/Format/template.html" is not a file in phar "mondrian.phar" in phar:///mondrian.phar/src/Transform/Format/Html.php on line 20
