F10 -> rawhide update failure

[nodata <lsof nodata co uk>]

Hello,

I tried this:
 yum update rpm
 yum update --skip-broken

but I get this:

Transaction Check Error:
  package audit-libs-1.7.12-3.fc10.x86_64 (which is newer than
audit-libs-1.7.12-2.fc11.i586) is already installed
  file /etc/libaudit.conf from install of audit-libs-1.7.12-2.fc11.i586
conflicts with file from package audit-libs-1.7.12-3.fc10.x86_64


I can't do an rpm -e --nodeps audit-libs due to this:
# ldd $(which rpm) | grep "not found"
	librpmbuild.so.0 => not found
	librpm.so.0 => not found
	librpmio.so.0 => not found

and I can't do a yum localinstall
rpm-libs-4.7.0-0.beta1.3.fc11.x86_64.rpm due to this:
warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 signature: NOKEY, key
ID d22e77f2


Public key for rpm-libs-4.7.0-0.beta1.3.fc11.x86_64.rpm is not installed

And preupgrade fails with a python traceback which I didn't save.

Any ideas?
