No answers for you, but I am very curious about this, too.

If I understand your question, this type of thing in a Cisco-context on 
their 6500/7600 units requires the use of a "set ip next-hop recursive" 
statement within a route-map stanza.  This forces Cisco to resolve the 
route of the distant "next-hop" in order to determine what the actual 
local next-hop should be.  Without the "recursive" keyword, the forwarding 
path of the packet can not be determined.

I wonder if Junos has a limitation here or a comparable method "under the 
covers" to resolve this issue.
