In the myspell-nl ebuill, we have
# thesarus has ugly name
mv th_nl_v2.dat th_nl_NL_v2.dat || die
mv th_nl_v2.idx th_nl_NL_v2.idx || die
# remove dutch translated license so it aint installed
rm -rf licentie* || die
Where the NL region is added to the nl language, probably in analogy with the names of the nl_NL.aff and nl_NL.dic files. However, these latter files are where the problem lies. The Dutch language (nl) is standardized across all regions where it is spoken, which includes Belgium (BE), so no region should be added. Rather, the NL region should be removed from the aff and dic file names.
I've reported this upstream <http://lists.sf.own-it.nl/pipermail/opentaal/2017-January/012204.html> and hope this will be fixed in a (hopefully) upcoming upstream version as well. N.B.: the download link is for non-thesaurus files is off-line due to website migration <http://lists.sf.own-it.nl/pipermail/opentaal/2016-December/012201.html>.
Unfortunately this package has no current maintainer - are you interested? https://wiki.gentoo.org/wiki/Project:Proxy_Maintainers

Perhaps. I'm in contact with upstream, who are planning to prepare a new release. At that point it makes sense to update the ebuild. (I think that the current source files are still mirrored on gentoo mirrors, so there is no urgency.)
