You have chosen to use the version of V8 found on your system
and *not* the one that is bundle with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with #{Libv8::VERSION} installed. You may
need to special --with-v8-dir options if it is in a non-standard
location
thanks,
The Mgmt
EOS
