I somehow missed this one.  Why are we disabling libcap?  And why are we 
adding another --enable flag when everyone has agreed that we should 
avoid that if at all possible?

It is especially on older systems that nfs-utils will break without 
libcap support.  Without CAP_NET_BIND, pmap_unregister() will fail when 
statd is shut down, leaving NSM registered with the portmapper, but with 
no active listeners.  When statd is started up again, it won't be able 
to register the new NSM listener ports.

That's the bug that was fixed by the addition of libcap.  I don't agree 
that is "quite minor."
