erasing the x86 version helps:
conary erase {libgnomecanvas,libbonoboui,gtk-qt-engine}"=[is:x86]"

the x86 version was introduced during the following update:

group-gnome-dist /foresight.rpath.org@fl:devel//2-qa/2.3.4.99_2010.07.13-0.2-1[~!bootstrap,~buildtests,~!cross,desktop,~!dom0,~!domU,~!gcc.core,~grub.static,ipv6,~kernel.debugdata,krb,ldap,pam,~!pie,readline,ssl,tcl,tk,~!vmware,~!xen is: x86(i486,i586,i686,sse,sse2) x86_64] ->
/foresight.rpath.org@fl:devel//2-qa/2.4.99+alpha+2011.01.25-0.1-2[~!bootstrap,~buildtests,~!cross,desktop,~!dom0,~!domU,~!gcc.core,~grub.static,ipv6,~kernel.debugdata,krb,ldap,pam,~!pie,readline,ssl,tcl,tk,~!vmware,~!xen is: x86(i486,i586,i686,sse,sse2) x86_64]

unfortunately that is not very specific. it was the first update after installing from an older image.

not sure what to do here other than finding out why the x86 version was added to the group and more importantly why it was not removed later (it obviously can't be part of the group now)
