Rebuild VMWare Fusion box for Ubuntu Server 12.04 to fix shared folders

I'm using [one of your boxes](http://puppet-vagrant-boxes.puppetlabs.com/ubuntu-svr-12042-x64-vf503-nocm.box) and [get this problem](http://superuser.com/questions/511679/getting-an-error-trying-to-set-up-shared-folders-on-an-ubuntu-instance-of-vmware) when I try to spin up a box.

Please can you rebuild the box with the packages pre-installed, or suggest a suitable workaround?
