Error installing 7.8.0.0 locally from build

Hello, I just built a fresh copy of 7.8 from the Mango/7.8.0.0 tag.

Everything went really well and the installation process completed, but when it tries to pull up the Sugar login page, I get a PHP error:

Fatal error:  Maximum function nesting level of '100' reached, aborting! in /Users/chad/Sites/sugarcrm/7800b/pro/sugarcrm/vendor/lessphp/lib/Less/Tree/Variable.php on line 30

 

Any ideas why this might be happening? Any one else seen this error?

 

Thanks!
