I took my slackpkg wwmkr and decompressed it and put it back in .tar.gz format
it will decompress to a folder named usr
just put /usr/bin/wwmkr.gambas and the other stuff where it goes
the depends for wwmkr are qt3 and gambas2-runtime; both should be available in portage
then try to start it in terminal for debugging
open a term and enter
if no error messages and it starts your good.
it uses an externel word processor like Abiword, Openoffice,etc
another good writing app is Pyroom
no formatting,etc, just a black screen!
Pyroom should also be available in portage
