Which is exactly what they want.  What you *really* want to do is:

   router bgp foo
   neighbor bar route-map prepend-this-you-fool in

   ip as-path access-list 66 permit _blah_blah_blah_blah_blah_blah_blah_blah_blah_

   route-map prepend-this-you-fool permit 10
   match as-path 66
   set local-preference 1000

-r
