This is the same thing I saw. It was a few days ago, I didn't write down 
exactly what I did to fix it and unfortunately I'm unable to reproduce 
this problem now.

All I can think of right now is that the policy.conf above appears to be 
built from a combination of the 1.17.30-3.2 and 1.17.30-3.9 sources.

The 1.17.30-3.2 version of domains/unconfined.te has:

define(`admin_tty_type', `{ tty_device_t devpts_t }')

(this definition can also be found in types/apache.te)

The 1.17.30-3.9 version of domains/unconfined.te has (at line 19):

typeattribute tty_device_t admin_tty_type;

If the "old" macro definition is still around somehow, this results in 
expanded text of:

typeattribute tty_device_t { tty_device_t devpts_t };

and there's the syntax error that appears in the error message above.

I haven't figured out how this happens yet, but someone with a 
still-broken system might be able to provide sufficient data to diagnose it.

Paul.
