wrong dependency chain ?

[Manuel Wolfshant <wolfy nobugconsulting ro>]

   While trying to do review for 
https://bugzilla.redhat.com/show_bug.cgi?id=473218 I found out that mock 
builds for rawhides bail out because of

Error: Missing Dependency: dejavu-lgc-fonts is needed by package rrdtool

 The same error is triggered by a koi scratch build. OTOH, dist-f11 
works just fine. Any idea why is rrdtool pulled in the the first place 
and why are the fonts missing ?
