Gentoo + rails + passenger + nginx

I installed ruby by compiling it myself (portage handled ruby doesn't quite do
it for me...). Then I installed the passenger gem 2.2.4. After installing
passenger gem went to the root passenger dir and ran "rake nginx" to get the
helperserver needed. Then I copied the nginx-0.7.61.ebuild and modified it to
include the use flag passenger. Then using the hint from the ebuild attached to
this bug got the full path for the nginx passenger module and put that into my
ebuild.

Then added the passenger use flag to /etc/portage/package.use for nginx and
emerged nginx 0.7.61 with passenger.

Added the config info to /etc/nginx.conf and I'm away everything works very
nicely :)
