Did you create the file in the cookbook's "files/default" directory?

http://wiki.opscode.com/display/chef/File+Distribution

Also, I suggest a couple changes to your resources, noted below:

I would use the "checksum" parameter in this resource to ensure that the file 
is not copied every time. You will need a SHA256 checksum, and can generate 
that. On linux, use sha256sum:

sha256sum VMwareTools.tar.gz

Mac OS X does not have a sha256sum binary, but you can generate the checksum 
with a Chef library :)

ruby -rchef/checksum_cache -e 'puts 
Chef::ChecksumCache.checksum_for_file("VMWareTools.tar.gz")'

Supply the full path to the .tar.gz if its not in the cwd.

I would have this be action :nothing with a "subscribe" meta-parameter on the 
cookbook_file resource.

subscribes :run, "cookbook_file[/tmp/VMwareTools.tar.gz]", :immediately

See: http://wiki.opscode.com/display/chef/Resources#Resources-Notifications

In both resources, you do not need the "puts" line, as Chef will display a 
message about the resource it is configuring at run time.
