selinux-policy appears to cause errors during a yum update

  Updating   : selinux-policy-3.10.0-64.fc16.noarch                        6/86 
/usr/share/selinux/devel/include/system/libraries.if: Syntax error on line 144803 ~ [type=TILDE]
/usr/share/selinux/devel/include/system/libraries.if: Syntax error on line 144805 ~ [type=TILDE]

Eek, later:

  Updating   : selinux-policy-targeted-3.10.0-64.fc16.noarch              24/86 
libsepol.policydb_read: policydb module version 14 does not match my version range 4-13 (No such file or directory).
libsepol.sepol_module_package_read: invalid module in module package (at section 0) (No such file or directory).
libsemanage.semanage_load_module: Error while reading from module file /etc/selinux/targeted/modules/tmp/base.pp. (No such file or directory).
/usr/sbin/semodule:  Failed!

During a subsequent "yum reinstall selinux-policy selinux-policy-targeted",
no errors were shown.  The previous versions were probably -3.10.0-46.fc16.
