Not sure what the tarextrat {} does, but wouldn't it be enough to
require => Exec["some_alias"] (I'd pop in an alias => "some_alias" in
the exec)?

Try a virtual resource
http://reductivelabs.com/trac/puppet/wiki/LanguageTutorial#virtual-resources
. Basically, you define the resource somewhere outside the define,
but it won't do anything on its own. You then put the realize function
in the definition, which will make the resource do something if it's
called at least once, but it won't bother puppet if the realize is
called more than once.
