Thank you for this; you have jogged my memory that I am missing
precisely those sources In the /etc/selinux/targeted/policy subdirectory
[root at cml policy]# pwd
/etc/selinux/targeted/policy

There is a file called policy.18

[root at cml policy]# ls -latrs
total 348
332 -rw-r--r--  1 root root 331417 Mar  8  2005 policy.18
  8 drwxr-xr-x  4 root root   4096 Aug 25  2005 ..
  8 drwxr-xr-x  2 root root   4096 Aug 25  2005 .
[root at cml policy]#

but there is no /etc/selinux/policy/sources subdirectory

The checkpolicy command is present:

[root at cml policy]# pwd
/etc/selinux/targeted/policy
[root at cml policy]# ls -latrs
total 348
332 -rw-r--r--  1 root root 331417 Mar  8  2005 policy.18
  8 drwxr-xr-x  4 root root   4096 Aug 25  2005 ..
  8 drwxr-xr-x  2 root root   4096 Aug 25  2005 .
[root at cml policy]#

So I am missing the source directory. I wonder if the missing components are
downloadable in rpm form...

Look for selinux-policy-targeted-sources.
