It looks like Enchant has been built with the voikko (Finnish) provider, but libvoikko is not installed.

I don't think it's possible to build Enchant's voikko provider without libvoikko installed, because the provider needs to link against libvoikko. So, this looks like a configuration problem on the user's system. To convince me otherwise would require a recipe to reproduce the problem, I think!

If there is a bug, it would definitely be in Enchant, and should be reported to Enchant's bug tracker (details in the package). Thanks!
