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 On Nov 16, 2010, at 7:11 PM, John Hendy wrote: > On Tue, Nov 16, 2010 at 5:46 PM, Mario E.
