[tahoe-dev] update on the buildbots

[zooko]

Folks, since all the tickets for Tahoe v1.4.0 are closed, I'm looking  
at the buildbots.

One of them is Dan's ArchLinux buildbot, which is still languishing  
in the Unsupported category because it used to mysteriously fail and  
then it mysteriously started succeeding.

A tahoe .egg?

I've noticed a clue.  See the difference between these two steps:

http://allmydata.org/buildbot/builders/Dan%20ArchLinux/builds/276/ 
steps/show-tool-versions/logs/stdio
http://allmydata.org/buildbot/builders/Dan%20ArchLinux/builds/277/ 
steps/show-tool-versions/logs/stdio

That warning message is due to divmod issue #2830.

So it seems like by step 277, when you installed Tahoe with  
easy_install then this also must have installed Nevow as an egg where  
back in 276 it was installed in some other way.  Does that make sense?

Do you think you could remove the current Nevow and then try re- 
installing Nevow using the ArchLinux installation process, to see if  
that makes the mysterious deep recursion in zope.interface recur?   
What is the ArchLinux install process for Python packages  
("distributions"), anyway?

Thanks!
