I tried a number of solutions outlined in previous answers, but found that running bundle (to install other, missing gems) would attempt to re-compile libv8 (despite having already installed it successfully using --with-system-v8) and thus suffer from the same issue.

Eventually, I found that removing the libv8 gem, fetching the gem file from rubygems, and then manually installing the .gem file with the --with-system-v8 flag worked for me.

i.e.

gem uninstall libv8
gem fetch libv8 -v LIBV8_VERSION
gem install libv8-LIBV_VERSION.gem -- --with-system-v8
bundle
