Chef binary was not found

I had to uninstall Vagrant 1.7.2 and downgrade to 1.6.5 (because of this issue) and now I'm seeing the following error message on initial vagrant up:

The chef binary (either `chef-solo` or `chef-client`) was not found on
the VM and is required for chef provisioning. Please verify that chef
is installed and that the binary is available on the PATH.

Not sure why I didn't run into this until now, but it looks like it can be fixed by adding:

config.omnibus.chef_version = :latest
