All, I have to admit I've been a bit late posting to the list regarding updates to Mercurial. As Erik has mentioned a couple of times, a 1.7.5 port was made last year (a factotum extension for http/https authentication was also written; see /n/sources/contrib/stallion/src/mercurial). This port has seen heavy use over the last year with a fair degree of success - I am finally comfortable making this a bit more public. stallion/mercurial is available via fgb's contrib. You will want to check /n/sources/contrib/stallion/src/mercurial/README before installing.
As for the current status, I'm working on a port for the latest stable (2.1.1 at the time of this writing). This should be complete soon - there are a few rough edges I want to polish first, particularly with documentation. This port should be a bit more complete than the last; I am aiming to have this become part of the official Mercurial distribution going forward. Jeff, I believe the biggest sore spot is the lack of a modern Python port. Ideally we could have a more complete port that wouldn't require APE, but that may be approaching the point of diminishing returns. Cheers, Steve
