I figured out what I had to do. I made the following change to
boostcpp.jam (around line 158):

        # Optionally add version suffix. On NT, library with version suffix will
        # not be recognized by linkers. On CYGWIN, we get strage duplicate
        # symbol errors when library is generated with version suffix. On OSX,
        # version suffix is not needed -- the linker expects the
        # libFoo.1.2.3.dylib format. AIX linkers do not accept version suffixes
        # either. Pgi compilers can not accept a library with version suffix.
        if $(type) = SHARED_LIB &&
          ! [ $(property-set).get <target-os> ] in windows cygwin darwin aix &&
          ! [ $(property-set).get <toolset> ] in pgi
        {
            result = $(result) ; #.$(BOOST_VERSION)  ;
        }

The BOOST_VERSION was being added to the end with no apparent option
to turn it off. Would love to see an option to turn this off.
