Right -- I was hoping to try to reach a decision this week with respect
to jessie.

Here's what I hope is a reasonably accurate summary of the situation.

As a general comment, people on #guile (including one of the upstream
Guile maintainers) have said that at this point, they would prefer that
we remove packages from jessie that support Guile 2.0 upstream, but
still depend on 1.8 in Debian (though we might or might not keep them in
unstable).  This was mentioned in particular, with respect to g-wrap,
guile-cairo, and guile-gnome-platform.

As an overall summary:

  - There are a few packages that we might want to remove from jessie
    for now (but they're likely to return later if/when they have an
    active maintainer -- guile-cairo, etc.[1]).

  - There's at least one package that has an active maintainer, and is
    actively being ported upstream, but that probably won't be ready for
    jessie (lilypond).

  - There are a number of packages that are more or less unmaintained,
    or may otherwise be unsuitable for continued inclusion in Debian.

  - Guile 1.8 is no longer maintained upstream, and hasn't been since
    2010.

[1] Though apparently g-wrap, guile-cairo, and guile-gnome-platform may
    be easy to NMU for 2.0 -- if I get enough time *immediately*, I
    might try to help there.  Anyone else interested should talk to Mark
    (cc'ed above).

In the end, the question is whether or not, on balance, we're better off
with or without guile-1.8 in jessie.

Some response from the maintainer in May, but nothing since:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707903

Last non-NMU appears to be 2012-05

I've also been told that drgeo no longer uses Guile upstream.

Only response wrt 2.0 is a mention of an upload that's been in
experimental for two years, but no response from the maintainer:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=761210

Last non-experimental upload: 2012-05

> guile-cairo [1]

Looks like this may just be waiting on a testing transition, which may
have been blocked by a (now fixed) problem with guile-2.0 on arm*.  If
so, it should just need a rebuild on arm*.

Though #guile warned that this NMU may or may not play nice with the
current guile-gnome-platform (below), depending on exactly how the NMU
was handled,

> gwave

This may be dependent on the guile-cairo update.

> lilypond

Upgrade to 2.0 won't be ready upstream in time for jessie, so removing
guile-1.8 would imply removing lilypond.

> texmacs

Last information was that upstream doesn't support 2.0 yet

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=731787

but texmacs may also not be currently suitable for Debian for other
reasons?

> swig2.0

I'm probably just missing something obvious, but I'm not sure why this
is still listed -- 2.0.12-1 appears to be in testing, and it is supposed
to have migrated to guile-2.0.  Looking in the control file I also don't
see any obvious guile-1.8 deps...

> graphviz

Hmm, "dak ... -s testing -Rn guile-1.8" doesn't list it, but maybe "-s
testing" isn't working right?  In any case, I imagine it's the swig dep
above.

> guile-1.8-non-dfsg/non-free

Should be removed iff guile-1.8 is.

Thanks
