No, it is not incumbent. Since this thread started (I know, there's only been a
few posts to it, but that still counts), I've worked with the x86 folks to bring
the keywords up to date for that platform. As a general rule, barring security
fixes and the like, something should be in the tree for 30-60 days before a
request to mark it stable can be filed. That said, I (and my fellow perl devs)
aren't perfect - its perfectly feasible and likely that we will miss modules
that are worthy of marking stable on your $arch (human volunteers and all that).
You are always welcome, as a user of Gentoo, to submit a bug requesting that
something go stable - if nothing else its a warm fuzzy that people are out there
and using stuff and actually in need of it (vs our guessing that folks are

Believe me, this is a feature I have in mind for 0.16 (0.15 is too far out the
door for this kind of addition). My frame of thought is comparing your
ACCEPT_KEYWORD against the needed ebuild's KEYWORDS and making a copy in your
overlay if necessary. That and actually documenting this disparity between
what's keyworded in the tree and what g-cpan's keyworded....

um, done :)

gripe at us :) those automated emails that get sent are to remind us of what's
getting behind in the tree. We try to tackle them as often as possible - but
other things crop up (i'm done giving excuses, don't worry)

eh? g-cpan shouldn't be overwriting existing ebuilds, and portage will only do
it if its in the PORTDIR - or do you mean when you manually bump? (If so, ignore
the entire comment block ending....<HERE>)

In that case, ping cab - I believe he's working with Michelle's overlay of
Catalyst to get it into portage.

I take requests for g-cpan :) Seriously, I feel like this email is degrading
rapidly, and will blame myself for being too defeneive the first time around.

When it was originally implemented, very. We were originally installing
everything to site, but were running into issues with core perl modules getting
sucked under and causing bad breakage. It's probably about time to re-examine
that patch (you're not the first to bring this up). Personally, at this point
I'd favor site_perl->vendor->core, so portage fills in above core, but what you
install manually overrides our ebuilds. Doesn't solve all of your problems, but
it would be a good step.

Thank you :)

eh, unfortunately not. Until all of CPAN is under a better qa watch, we still
have to do manual qa and file rt bugs like everyone else (and I have a score or
two open right now). While some modules are 'trustworthy' for bumping, not all
again, sorry for the huge delay in responding,
