loux, your ebuild packet sucks...
i had very massiv problems with the cal3d version from you. (cal3d-0.12-r493 )
so i must delete the folder and resync, all things from planeshift ebuild got deleted.
download the ebuilds at http://loux.thefuture.free.fr/portage.tar.bz2 and uncompress them inside /usr/local/portage (added to PORTDIR_OVERLAY)
unkeywords them :
echo "dev-games/crystalspace-ps" >> /etc/portage/package.keywords
echo "dev-games/cel-ps" >> /etc/portage/package.keywords
echo "games-rpg/planeshift" >> /etc/portage/package.keywords
echo "games-rpg/planeshift-art" >> /etc/portage/package.keywords
and compile : emerge planeshift
finally install the art : emerge planeshift-art
thats wrong, too.
cal3d-0.12-r493 is masked, but when you add this to your packages.mask and try again, it doesn't work.
then came the output that the version of cal3d-0.11.-r1 is okay, too.
you can't emerge it, but it is in the normal portage tree.
// uncompress them inside /usr/local/portage
i uncompressed them inside /usr/portage/ because it doesn't work when you extract these files in /usr/local/portage
the main error was a failture in the manifest of the cal3d ebuild.
repair the ebuild, use more portage tree versions or write a functioning tutorial.
