Milestone:  Boost 1.41.0                       |   Component:  Building Boost
  Version:  Boost 1.40.0                       |    Severity:  Problem       
 Keywords:                                     |  
-----------------------------------------------+----------------------------
 Boost 1.40.0 has internal library dependencies (e.g.,
 libboost_filesystem.so depends upon libboost_system.so) that I wanted to
 be able to automatically satisfy at run-time via RPATH.  The most
 straightforward way to do this would be to embed an RPATH of
 $ORIGIN/../lib in the shared libraries (or even, more simply, $ORIGIN).

 Unfortunately, there is no way that I could discern to modify project-
 config.jam to escape $ORIGIN so that it would get passed through to the
 linker.  I attempted to change the gcc toolset line to

 if ! gcc in [ feature.values <toolset> ]
 {
     using gcc : : : <dll-path>\$ORIGIN/../lib <linkoptions>-z origin ;
 }

 but no matter what combination of single quotes, backslashes, etc., that I
 tried, $ORIGIN got evaluated as an empty shell variable, and I'd end up
 with /../lib as my RPATH.

 In desperation, to move forward with my project, I hacked gcc.jam
 directly, and that produced the desired effect, but obviously, this is not
 a production-quality solution.
