Actually you'll find its functionally the same but a lot of the "bones" 
that show through in FC4 and earlier now remain hidden:

1) Use audit2allow to create a local ruleset.
2) Compile and load the local ruleset.
3) See if the local ruleset accomplishes what you wanted.  If not, go to 
step 1 and repeat.

The FC4 method just meant you also had to unpack the whole targeted 
ruleset and remake it in order to add the local ruleset.  On the other 
hand, you get to see what's "under the hood" even though most people 
doing this would leave it alone.  The FC5 approach lets you just tack on 
a local policy.

Also, I noticed that the article in the link mentions that "/!\ You need 
to have have the checkpolicy package installed to build policy 
modules".  Is that a different RPM that the OP will need?

Cheers,
Dave
