In-Reply-To: Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII I've tried installing this, but it seems to only come up with the 2.2.5-BETA release. The 3.0-971010-SNAP directory seems to be containing 2.2.5-BETA stuff. The 3.0-971012-SNAP directory in not available to cd to. What's up ?
