Description of problem:
xfce4-dict actually prefers "enchant" over "aspell" if it is available, which is a good thing as it fits with the fedora policy for dictionaries (http://fedoraproject.org/wiki/Releases/FeatureDictionary) and gives the same suggestions and language support as in OpenOffice.org/Firefox/Evolution etc.

So we should require enchant instead of aspell to reflect xfce4-dicts preference


Version-Release number of selected component (if applicable):
