Comment(by trog24@…):

 There are three different behaviors to the linkage failure as I noted in
 the discussion list before filing the bug report.
 Failure 1 when linking to the /usr/local/lib Boost using the suffix
 -xgcc40-mt libraries is:

 {{{

 Failure 1 when linking to the /usr/local/lib Boost using the suffix
 -xgcc40-mt-1_37 libraries is:

 {{{

 }}}

 and failure 3 when linking to the /opt/local/lib Boost libraries
 (MacPorts) is:

 {{{
 g++ -D_THREAD_SAFE -g -O2 -o .libs/browser browser.o -Wl,-bind_at_load
 -L/usr/local/spidermonkey/lib/ -L/opt/local/lib ./.libs/libtest-openvrml.a

 make[1]: Leaving directory
 `/Users/frank/FirefoxDownloads/openvrml-0.17.11/tests'
 make: *** [check-recursive] Error 1
 }}}

 with the differences between the three being:

 Failure 1 includes:

 {{{
 /usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: warning can't open
 dynamic library: libboost_system-xgcc40-mt-1_37.dylib referenced from:
 /usr/local/lib/libboost_filesystem-xgcc40-mt.dylib (checking for undefined
 symbols may be affected) (No such file or directory, errno = 2)
 }}}

 Failure 2 includes:

 {{{
 /usr/bin/ld: can't locate file for: -lboost_system-xgcc40-mt-1_37.dylib
 }}}

 in their respective error message sequence when when trying to link.  In
 these two case, ld cannot cannot find the designated dependent library
 even though the library exists within their respective directories as
 indicated by all being resolved using:

 {{{
 make check LIBPATH="-llibboost_system-xgcc40-mt", make check LIBPATH
 ="-llibboost_system-xgcc40-mt-1_37", or make check LIBPATH
 ="-llibboost_system-mt" respectively.
 }}}
