Please mark openttd-1.2.2.ebuild stable.
amd64 tested ok (builds, runs)
I also suggest to add "|| die" to lines 105 & 107 in the ebuild (for the two rm -f commands).
amd64 stable
x86 ok ( builds ok, test ok, run ok ) but repoman says : portage.internal games-simulation/openttd/openttd-1.2.2.ebuild: 'prepalldocs' called on line: 108 RDEPEND.implicit games-simulation/openttd/openttd-1.2.2.ebuild: RDEPEND is not explicitly assigned
