This seems almost an oversight. There is a patch sage-conf-9.8.patch but the ebuild for 9.8 currently search for a version 9.7 patch. I've tried to modify the ebuild to choose the correct patch file sage-conf-9.8.patch provided with current version but it doesn't build. So I've recovered the old sage-conf-9.7.patch and added to files filder and I've been succesful building sage-conf 9.8. I'm curently re emerging sage 9.8 to check. However the issue is not if sage builds or wont builds this should be fixed. Thanks for your patience.
