Generated environment file missing some variables

[mhale]

I have been having an issue with Passenger not loading the gemset correctly for Rails applications in RVM 1.25.x. This occurs because I am using a config/setup_load_paths.rb file as recommended here:

https://rvm.io/deployment/passenger3

The MY_RUBY_HOME variable is not being set in the environment file, so RVM never switches to the correct gemset. In my case, it was missing from:

/usr/local/rvm/rubies/ruby-2.0.0-p353/lib/ruby/gems/2.0.0/environment

The content of that file looked like this after I did "rvm install ruby-2.0.0-p353":

export PATH="/usr/local/rvm/gems/ruby-2.0.0-p353@global/bin:/usr/local/rvm/rubies/ruby-2.0.0-p353/bin:$PATH"
export GEM_HOME='/usr/local/rvm/gems/ruby-2.0.0-p353@global'
export GEM_PATH='/usr/local/rvm/gems/ruby-2.0.0-p353@global'
export IRBRC='/usr/local/rvm/rubies/ruby-2.0.0-p353/.irbrc'
unset MAGLEV_HOME
unset RBXOPT

Adding MY_RUBY_HOME with the correct value and restarting Passenger fixes the issue. This issue occurs in every version of 1.25.x that I've used, so I don't know when it was introduced. I can confirm that it happens in 1.25.14 (latest release) and is reproducible.

The output of rvm info is:

Btw, I backed the RVM 2.0 Bountysource fundraiser, congratulations on completing it.

ah sorry, I thought we did not needed those, the above commit restores it, you can:

rvm get head         # update rvm
rvm gemset reset_env # fix the environment file (and wrappers)

Brilliant, thanks!
