Ruby, RVM and Mountain Lion

Key problems

Mountain Lion (10.8) has three main difference compared to Lion (10.7):

XCode 4.4 does not install Command Line Tools by default
X11 isn't available anymore
The installed version of OpenSSL has some bugs

How to work around

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	// force certain pages to be refreshed every time. mark such pages with
	// 'data-cache="never"'
	//
	jQuery('div').live('pagehide', function(event, ui){
	var page = jQuery(event.target);

	if(page.attr('data-cache') == 'never'){
	page.remove();
	};
	});
