It is recommended not to do this.  Some of our users are behind 
firewalls and cannot fetch except via HTTP and FTP.  Instead, you need 
to create your own tarball of the sources checked out from the VCS, 
possibly using a "helper" makefile target that fetches from VCS and 
creates the tarball for republication by you on MASTER_SITE_LOCAL.
