Linux.  Here's what I get:

The above was after just pulling and updating the submodules.

After again checking out develop in libs/filesystem and re-invoking b2 
it works:

llc[60]$ 
../../../bin.v2/tools/inspect/build/gcc-4.6/release/link-static/inspect 
/opt/boost/libs/timer -text -brief
Boost Inspection Report
Run Date: 23:15:28 UTC, Thursday 26 December 2013

Totals:
   27 files scanned
   14 directories scanned (including root)
   21 problems reported

[other output elided]

So on Linux at least there seems to be another dependency.
