Another issue.  We definitely need a variant of one patch from the current
boost version:

         {
             result = $(result).$(BOOST_VERSION)  ;

Without this patch we get the following:
$ readelf -a /usr/local/lib/libboost_program_options.so.4| fgrep SONAME
 0x000000000000000e (SONAME)             Library soname:
[libboost_program_options.so.1.48.0]

But the libraries are installed as .so and .so.4 (current BOOST_SHARED_LIB_VER).
Because of the SONAME the run-time linker seems to look for .so.1.48.0 files.

Another approach to patching this issue could be replacing $(BOOST_VERSION)
with a value of BOOST_SHARED_LIB_VER, so that SONAME entry has a .so.4 form.

With the above path the do-install target for shared libs should be changed to
this:
do-install:
# Install libraries
.for lib in ${BOOST_LIBS}
        ${INSTALL_LIB} ${WRKSRC}/stage/lib/libboost_${lib}.so
${PREFIX}/lib/libboost_${lib}.so.${BOOST_SHARED_LIB_VER}
