Problem solved with gem install libv8 on FreeBSD 10.2

This is the output of running the command ‘gem install libv8’:

the result is :
An error occurred while installing libv8 (, and Bundler cannot continue.
Make sure that `gem install libv8 -v ‘’` succeeds before bundling.

problem solved :

sudo gem install libv8 -v '' -- --with-system-v8

then ….

Building native extensions with: '--with-system-v8'
This could take a while...
Successfully installed libv8-
Parsing documentation for libv8-
Installing ri documentation for libv8-
Done installing documentation for libv8 after 1 seconds
1 gem installed

and finally again running …bundle install

$bundle install 

Hope that helps!
