Milestone:  Boost 1.38.0                   |   Component:  Building Boost
  Version:  Boost 1.37.0                   |    Severity:  Problem

-------------------------------------------+--------------------------------
 This is on FreeBSD 6.1, where the rpath of an executable is separate from
 the rpaths of the shared libraries it links with.

 I have built boost 1.37.0 and installed it in a private directory, for use
 with another project. After linking the other project, I examined it with
 ldd to check if I had got the library search paths correct.

 I found that although some boost libraries could be found, one was not
 found (libboost_system-gcc42-mt-1_37.so.1.37.0).

 It turned out that libboost_system-* was required by
 libboost_filesystem-*, but since there was no RPATH option specified when
 linking, it was not found.

 I worked around it by re-linking libboost_filesystem-* while the
 environment variable LD_RUN_PATH was set to the private library directory.
 A proper solution would pass --rpath (or equivalent) to the linker.
 (Unfortunately how to pass this option varies somewhat between systems:
 -R, -Wl,-R, -Wl,--rpath, -wL,-rpath, etc etc)
