Hi John,

Apologies for having stupidly done some hacky development work on the  
master branch of org-article.  You must have pulled this weekend when  
things were *really* unsettled.  The errors you're getting now are  
ones I introduced but have since fixed.

The python dependency is from a work in progress that will eventually  
(and hopefully) support the minted package for source code markup and  
typesetting.   This is the kind of thing that should live in a git  
branch before it ends up throwing errors around your workspace.  So,  
more apologies.

I'll work at getting all the development stuff into a branch so master  
is stable again.

All the best,
Tom
