1) Talking about Debian "stable" is problematic, especially
 in a discussion that will be archived.  The currently stable
 release is Debian lenny, released September 5th, 2009.

 The next release will be called squeeze.  It is currently
 in the "testing" phase.

2) The following observations may be useful, even though they
 don't directly respond to the question that was asked.
 Squeeze (at the moment at least) is providing boost 1.35 
 which in turn provides
    /usr/include/c++/4.3/unordered_map
    /usr/include/c++/4.3/debug/unordered_map
    /usr/include/c++/4.3/tr1/unordered_map
    /usr/include/c++/4.3/tr1_impl/unordered_map

 On the other hand, trying to compile simgear on Debian
 squeeze fails.  So apparently something higher than 1.35
 is required ... and simply checking for the aforementioned
 files is not a sensitive test.  I note that Effect.hxx is
 trying to include boost/unordered_map.hpp as opposed to
 tr1/unordered_map, so we are not surprised that the check
 is not sensitive.  If the code could be rewritten to use
 tr1/unordered_map, then perhaps users could get by with 
 boost 1.35 or even less ... which would be a Good Thing.
 Introducing additional dependencies into FGFS makes 
 extra work for a lot of people.
