Compiles and works on my system (using arm/13.0/armv6j profile and default USE flags). Are more positive feedbacks/tests/details needed to keyword this package with ~arm?
i can also confirm it works with 1.3.x, armv7
~arm keyword added, closing. 11 May 2013; Markus Meier <maekke@gentoo.org> nginx-1.4.1-r1.ebuild: add ~arm, bug #456752
