"brew install mame" command fails svn checkout (operation timed out), it seems there is a new MAME/MESS SVN server.
Quoting from http://mamedev.org/?p=373 :
["21 Aug 2012
We're pleased to announce our new publicly-facing MAME/MESS SVN server located at: svn://dspnet.fr/mame/trunk
When contributing code, please base your changes on the latest code found on the SVN server."]
mess/mame: update svn url
