[Puppet Users] Strange Issue with Symlink

I'm seeing a strange issue with symlinks in Puppet 2.7.19.
File {
ensure => directory,
owner => apache,
group => apache,
}

file { "/mnt/${site_name}":
mode => 0660,
}

mount { "/mnt/${site_name}":
ensure => mounted,
atboot => true,
device => "${drupal_nfs_host}:${drupal_nfs_vol_root}",
fstype => "nfs",
options => "rw,vers=3,timeo=60,nosuid",
require => File["/mnt/${site_name}"],
}

file { "/var/www/${site_name}/${drupal_shared_reldir}":
ensure => link,
target => "/mnt/${site_name}",
require => [Mount["/mnt/${site_name}"],
File["/var/www/${site_name}/${drupal_shared_reldir}"]],
}

I run the agent on my node. The mount directory and mount point are setup
correctly. However, the symlink is completely ignored. (I've replaced
actual paths with the vars used above for privacy.)

notice: /File[/mnt/${site_name}]/ensure: created
notice:
/Stage[main]//Node[NODE_NAME]/Market[${site_name}]/Mount[/mnt/${site_name}]/ensure:

As you can see, there were no messages related to
File["/var/www/${site_name}/${drupal_shared_reldir}"].

The crazy part is that a test link does work.
file { "/tmp/test-link":
}

file { "/tmp/link":
ensure => link,
target => "/tmp/test-link",
require => File["/tmp/test-link"],
}

Any thoughts on what's happening? It seems odd that there are no error
messages.

Thanks,
