Vagrant up fails because of the vagrant-berkshelf

I've found out the solution. See the 1st comment.

Hi.
I've just tried to start a standalone vagrant-mesos.
I've installed all the software required:

$ aptitude versions chefdk vagrant virtualbox
Package chefdk:                        
i   0.5.1-1                                                                                                                                                                                        100 
Package vagrant:
i   1.4.3-1                                                                                                  trusty                                                                                500 
Package virtualbox:
i   4.3.10-dfsg-1ubuntu4                                                                                     trusty-updates                                                                        500 

$ vagrant plugin list
vagrant-berkshelf (4.0.3)
vagrant-cachier (1.2.0)
vagrant-hosts (2.4.0)
vagrant-omnibus (1.4.1)

But the vagrant up command still fails

.../standalone$ vagrant up
Failed to load the "vagrant-berkshelf" plugin. View logs for more details.

I've upgraded vagrant to the latest version (1.7.2) and it worked well.
Seems that the ubuntu 14.04 officially distributed vagrant (1.4.3) is not supported by this repo.
Maybe should add a note about min version in the prerequisites?

Hi! Firstly, thank you for trying this project!

Maybe should add a note about min version in the prerequisites?

I explicitly wrote the prerequisites in README.md.

• vagrant 1.6.5+: http://www.vagrantup.com/
