Yeah, that last bit doesn't look like a "miscellaneous other fix" to me.
OTOH, if this is going to happen, it's going to need better configure logic 
than was removed.  These days, while it's a good idea to look for 
/usr/afsws for completeness, you're almost never going to actually find the 
AFS libraries there.  Of course, if you go the libkrbafs/libkafs route, 
you're not going to need the AFS libraries, either.

To answer a previous question...

As always, libkafs is distributed with Heimdal <http://www.h5l.org/>, 
primarily for Kerberos/AFS integration (it's primary purpose is to provide 
an interface for getting and installing AFS credentials, given Kerberos 
tickets, for use by programs like login).

I'm not sure what the status of libkrbafs is.  Red Hat distributes it with 
their operating systems (free and commercial), but it didn't originate with 
them.
