Artha is a off-line dictionary based on WordNet.
This is a interesting project, I was trying to make an ebuild but I wasn't quite sure what to do.
This hasn't been thoroughly tested, but it worked with OpenOffice.org on x86 and amd64.

ebuild for artha-1.0.2
Works for me. You should keep amd86 and x86 keyworded though. Care to add it to sunrise?
