this version is known to compile against v8 3.15.12 here are the approximate steps:

if [ /bin/arch -m == 'i86pc' ] ; then ## solaris will not compile, you'll need to use the original 0.07 version of Javascript up on CPAN from DGL ## then use the libcsw libv8 packages elif [ /bin/uname -m == 'x64_64' ] ; then ## 64 bit make x64.release library=shared soname_version=3.15.12 /bin/cp -v out/x64.release/obj.target/tools/gyp/* /usr/local/lib /bin/cp -v include/* /usr/local/include/ /bin/ln -fs /usr/local/lib/libv8.so.3.15.12 /usr/local/lib/libv8.so ldconfig elsif [ /bin/uname -m == 'i686' ] ; then ## 32 bit make ia32.release library=shared soname_version=3.15.12 /bin/cp -v out/ia32.release/obj.target/tools/gyp/* /usr/local/lib /bin/cp -v include/* /usr/local/include/ /bin/ln -fs /usr/local/lib/libv8.so.3.15.12 /usr/local/lib/libv8.so ldconfig fi
