Attached are ebuilds for GNUMail-1.03 and Pantomime-1.0.5, they are in categories app-gnustep and lib-gnustep respectively, you must specify app-gnustep when emerging, like this: app-gnustep/GNUMail. The gnustep eclass is required: Bug #14131
Created attachment 7410 [details] GNUMail and Pantomime ebuilds GNUMail-1.0.3 Pantomime-1.0.5
I don't have time to look at the gnustep/windowmaker stuff at the moment :(
app-gnustep/gnumail-1.1.0_pre2 has been added to portage.
*** Bug 18075 has been marked as a duplicate of this bug. ***
Not quite a duplicate... His has optional components. Also, I believe that Pantomime doesn't qualify as an application, perhaps dev-gnustep or lib-gnustep would be a better choice...
I am putting all gnustep applications into one directory right now... split off if the environment matures into something like kde or gnome in size.
In any case, it looks like you forgot to update the /usr/portage/profiles/categories... "app-games app-i18n" Where is app-gnustep?
