Shouldn't this be -lboost_system-xgcc40-mt-1_37 (no .dylib)
Also, why is it in a different place from the other libs?

There is not an -lboost_system-xgcc40-mt-1_37 input to g++ when this  
occurs, so, it had to be gotten from somewhere else, either internal  
to g++ which is unlikely or from libboost_filesystem_xgcc40-mt-1_37.

All Boost libraries are in /usr/local/lib where they are suppose to  
be.  This is verified by the command:

        make check LDFLAGS='-lboost_system-xgcc40-mt-1_37'

successfully finding libboost_system-xgcc-mt-1_37.dylib.
        Come think of it, there is also a libboost_xxx-xgcc40-mt set of  
Boost libraries from an earlier install that gave the exact same  
error message when libboost_system_xgcc40-mt is not specified which  
would indicate that somewhere within libboost_filesystem_xgcc40-mt  
and libboost_filesystem_xgcc40-mt-1_37 is an improper link direction  
generated by the Boost library build that is overridden by the  
LDFLAGS input.
