How to get rvm running inside fcgi?

I had a rails 2.3 application running on apache + fcgi, and I am migrating it to rails 3.1 + rvm (+ apache + fcgi).

I am now blocked at fcgi <-> rvm.

I tried putting #!/usr/local/b开发者_StackOverflow中文版in/rvm 1.9.2@rails31 exec rubyinside my public/dispatch.fcgi.

Running /usr/local/bin/rvm use 1.9.2@rails31 exec ruby /some_path/current/public/dispatch.fcgi from my command line works fine, but the apache log shows:

ERROR: Unrecognized command line argument(s): '/some_path/current/public/dispatch.fcgi ' ( see: 'rvm usage' )

Any idea of what is going on ? How should configure things to make this work ?

Thanks for your answers.

Haven't tried myself but how about something like

#!/usr/bin/env /usr/local/bin/ruby-1.9.2-p180
