I copied instead of linking the speller hfstol file, but it did not help.

This is one possible source of error, since I'm still using the Finnish one - it might not be a nice subset. How is this transducer made?

So I would think as well.

It does. In my LibreOffice installation I have access to all OOo spellers + the ones installed on the system, ie spellservice spellers of all kinds.

Understandably. I assume that this work will also benefit a broader user group over time, as the oxt work is basically language independent and can be integrated with the voikko oxt code base later on?

I am happy to play with whatever Greenlandic oxt you have, if you need more testing:)
