Puppet users - Oct 2007 - file type to monitor files recursively and ignore dir timestamps

I have a manifest that looks for changes in files recursively and 
restarts a service should it find any changes.  Problem is that i 
''ignore'' some files that i do not wish to monitor and ones
that change
occasionally and when they change it modifies the timestamp on the 
directory which in turn triggers puppet to restart the service.

So is there a way to monitor only file checksums recursively and ignore 
timestamp changes to directories?

Maybe a complementary parameter to the ''ignore'' parameter of
the ''file''
type, like ''include'' or ''only'', that accepts
wildcards like ''ignore''?

Here is an example of the offending manifest:

    [ "/etc/dansguardian/lists/blacklists",
    "/etc/dansguardian/lists/phraselists" ]:
        recurse       => true,
        ignore        => "*.processed",
        checksum      => md5,
        notify        => Service["dansguardian"];
