I am working on building a project that relies on OpenSG2 and VR Juggler 
2.2 for various reasons between the two I am building Boost 1_37 for 
the  boost co dependency.   While working with VR Juggler I noticed the 
error that boost::filesystem::exists was not defined in 
libboost_filesystem-xgcc40-mt.dylib.  Which I found a little odd.  After 
looking in to it I noticed that it is indeed not defined in either on of 
my release libs, but was defined in all of the debug libraries.  In case 
I had done something wrong when I compiled boost I started a recompile 
with the following options.

bjam --tool-set=darwin --prefix=$HOME/usr  -- build-type=complete -a stage

It currently looks like the build will yield the same results.  I have a 
few nm | grep | c++filt  below for  the new libs.  So I have two 
questions.  Is the behavior below normal.  If not what might be the cause?
