Re: [Xen-devel] compiling error "xen-unstable.hg"

You have dropped xen-devel again. I have put it back again this time. In
the future I will ignore mails from you which do not CC the list.

Which indicates version 1.0.12 of yajl, yet the git URL you quoted
before contains 2.0.5.

I think you've got your system into an inconsistent state, with multiple
incompatible versions of yajl on it.

This implies a 2.0.x version also.

Yes, you need to clean up all the rubbish you installed by hand and make
sure your system is in a consistent state before you try installing Xen
again. I suggest you ask for help on how to do this from the Ubuntu user
forums or somewhere like that -- it's not a Xen issue.
