So long as Xen uses python as part of the build system (which I think it will do for the foreseeable future) I don't think it is optional and therefore the --disable-pythontools is broken as currently implemented. I think we should just remove this option for 4.2 and revisit being able to disable the runtime components which use python, but not the build time usage. --disable-pythontools is a bit of a big hammer since as well as disabling xend (which seems reasonable) it also throws out pygrub which people are more likely to want. In 4.3 we should aim for more fine grained control of those two options. In the meantime I think the answer is "don't do that then". That may well also turn out to be the answer for the 4.2.0 release at this point. A patch to remove this option follows.
