Greetings Paul. Since I was the one who made the comment, I'll be the
one to explain it. :-)
The tool in particular that we were looking for is integration with
Trac (http://trac.edgewall.org/). We use Trac for all of our bug
tracking, and we have a bunch of wiki pages on it as well. When last
we looked (several months ago -- which admittedly may be a little out
of date now; see below), the Trac+hg integration was a bit weak.
IIRC, Mercurial was still v0.9.something, too (although it's well past
v1.0 now). I have a dim recollection of asking about Trac+hg on the
mercurial mailing list at the time (I'm not 100% sure I did, but I
*think I did...?). But regardless of whether I did or not, I remember
that we were definitely under the impression that Trac+hg integration
would be up to us; we unfortunately didn't (and still don't) have the
time/resources to do it. :-( So we adopted a wait-n-see attitude.
We then definitively shelved the "let's change repository technology"
discussion until after Open MPI v1.3.0 was released. Unfortunately,
releasing OMPI v1.3 took a *lot* longer than we expected. :-( If
Murphy doesn't rear his head, we'll release v1.3.0 next week. I think
this then opens the door to the discussion of switching repository
technologies again.
That being said, even if the developer community decides "yes, let's
move to Mercurial", it'll probably take us a little while to do so --
there's infrastructure changes at Indiana University that would need
to occur (our hosting provider), web pages to update, automated
scripts to update, etc. I'm definitely in the "let's switch" camp,
but we'll need some careful planning and execution to make it happen.
FWIW, we do maintain an official Mercurial mirror of the Open MPI SVN
repository, and several of us use Mercurial for short- and long-term
development branches (merging back to the SVN trunk when done). See
here:
http://www.open-mpi.org/hg/hgwebdir.cgi
And here:
https://svn.open-mpi.org/trac/ompi/wiki/UsingMercurial
So to be honest, I haven't done my homework to see if Trac+hg
integration is a solved issue these days. If it is, it makes our
discussions easier. :-) If not, that might be somewhere that we need
some help.

I was listening to FLOSS Weekly and I heard it commented the Open
MPI development team was "waiting for a few more tools to get a
little more mature" before moving completely over to Mercurial. Does
anybody enumerate what is meant by that comment? Is there anything
that the Mercurial community do to help?
