I cannot log in after installing MODX Revolution

After installing MODX Revolution I cannot log in - just a blank page is displayed. My setup: MODX downloaded from git, PHP 5.3, Apache 2.2, OS ubuntu.

In apache error log I see this message:

Actually, Paul Graffam is right in the comments, when building from git (either through a clone or download from github), you need to run transport.core.php as well as some other things the first time you do it.

Specific instructions can be found here: http://rtfm.modx.com/display/revolution20/Git+Installation

An alternative if you don't want to go through those steps is to download a nightly build from http://modx.com/download/nightlies/ - you can install them as normal there.

(Realise I'm a bit late to the question, but figured others might stuble across it in the future and there's no answer yet)
