[...] our passenger (3.0.8) and nginx are blocking environment variables from being passed to Ruby. We ended up with wrapping the ruby invokation in passenger as follows: #!/bin/sh export LANG=en_US.utf8; [...]

I don’t think this has been documented anywhere else better than this blog post?

Regarding REE GC tuning env, it looks like recent versions of passenger under RVM install using a wrapper with an ‘environment’ file already. For instance, wrapper (included as PassengerRuby in passenger apache output) at:

/usr/local/rvm/wrappers/ree-1.8.7-2011.03/ruby

and that script already sources a bash file setting ENV at:

/usr/local/rvm/environments/ree-1.8.7-2011.03

So i think REE GC tuning env can conveniently be put in that ../environments/… file? Not sure if ‘export’ is needed, I think it’s not, but I used it anyway just to be safe.

Some updated documentation on this stuff would be awesome.

FWIW: I wasn’t able to use mod_env to modify PATH using SetEnv. According to docs here: http://httpd.apache.org/docs/current/env.html it looks like PATH might get cleaned after mod_env.

For any of you struggling with the Ruby 1.9.1 lack of support for passing the GEM_PATH in the environment variable, if you use the wrapper method outlined above it works.
