@y-p thanks...lmk any more you see

@yarikoptic, can you kickoff a build on buildbot to verify the fix?

@jreback, afaict windows is green and if sparc is too and @jtratner zaps the remaining rpy2
issues I think we should send a release heads-up to the guys on pandas-dev. If no objections
in time for the milestone, we should tag 0.13 final and move on. The ANN and binaries can follow
in due course.

I bumped the milestone a few days to give the badgers time to raise a flag if needs be.

Sound ok to you?

[jreback]

ok by me

thought @changhiskhan was going to tag 0.13rc2

but ok as is

[yarikoptic]

@y-p buildbot should start automatically when it frees up from other builds... or is this fixed not in master?

ps I will check in detail when return from children museum ;-)

@yarikoptic, my bad, ofcourse buildbot is automatic. I was fooled by latest build on 25, but that
was just the last commit...

Enjoy the museum :)
