Building changeset...error: The group flavors that were cooked changed from the previous cook.
The following flavors were newly cooked:

     ~!VMwareTools-kernel.debug,~!VMwareTools-kernel.numa,~!VMwareTools-kernel.smp,X,~!alternatives,~!bootstrap,~!builddocs,~buildtests,desktop,~!dom0,~!domU,emacs,gcj,~glibc.tls,~!grub.static,gtk,ipv6,~!kernel.debug,~kernel.debugdata,~!kernel.numa,~!kernel.pae,krb,nptl,pam,pcre,perl,~!pie,python,readline,sasl,~!selinux,~sqlite.threadsafe,ssl,tcl,tk,vmware,~!xen,~!xorg-x11.xprint is: x86(i486,i586,i686,~!sse2)

With the latest conary, you must now cook all versions of a group at the same time.  This prevents potential race conditions when clients are selecting the version of a group to install.
(Add the --allow-flavor-change flag to override this error)
