Internal libboost dependency failure at reference time.

[trog24 (Frank J. R. Hanstick)]

The following error occurs when trying to link openvrml to libboost:

g++ -D_THREAD_SAFE -g -O2 -o .libs/browser browser.o -Wl,-bind_at_load  -L/opt/local/lib ./.libs/libtest-openvrml.a /Users/frank/FirefoxDownloads/openvrml-0.17.12/src/libopenvrml/.libs/libopenvrml.dylib -L/opt/local/lib/firefox-2.0.0.20 /opt/local/lib/libjpeg.dylib /opt/local/lib/libpng12.dylib /opt/local/lib/libfontconfig.dylib /opt/local/lib/libiconv.dylib /opt/local/lib/libexpat.dylib /opt/local/lib/libfreetype.dylib -lz -lmozjs -lplds4 -lplc4 -lnspr4 -lboost_thread-mt -lboost_unit_test_framework-mt -lboost_filesystem-mt
/usr/bin/ld: Undefined symbols:
boost::system::get_system_category()
boost::system::get_generic_category()
collect2: ld returned 1 exit status
make[2]: *** [browser] Error 1

make[1]: *** [check-am] Error 2
make[1]: Leaving directory `/Users/frank/FirefoxDownloads/openvrml-0.17.12/tests'

The undefined symbol references get_system_category() and get_generic_category() are in libboost_filesystem-mt and the symbols are defined in libboost_system-mt and not in some unrelated library; yet, libboost_filesystem-mt cannot find libboost_system-mt to resolve the undefines, a library libboost_filesystem-mt is dependent on even though the libboost_system-mt is part of the same set without a supplied reference, ie:

make check LDFLAGS='-lboost_system-mt'

This particular dependency should have been resolved during the Boost build process. The above command is the work around until the problem is resolved.
