Created attachment 22189 [details] spe-0.4.2c.ebuild
Created attachment 22190 [details, diff] spe_setup.patch This patches the file setup.py that it doesn't ask the user something if an old spe installation is found.
I added SPE 0.4.2c to portage. Thanks you for providing the ebuild.
The file spe_setup.patch is missing in the portagetree, i.e. in .../dev-util/spe/files (it's a gentoo-only patch).
Somebody else already pointed out to me that I forgot to add the patch. The patch have just hit the rsync mirrors by now.
