they are 0555 instead of 0755
ebuild sets perms to 0775 at line 109. suggest status -> resolved.
I can't reproduce this and the ebuild clearly sets the permissions to 775. Reopen if you can reliable reproduce this.
I'm not sure how you could reproduce it as it's clearly a ppc64 problem ;-)
in the current crop of ppc64 livecds this is correct
stick a fork in it!
