It might be worth trying .bashrc -- .bash_profile is specifically for 
interactive logins -- but that won't work if they're using /bin/sh.

Another possibility is /etc/environment, though I remember that not working...

Worst case, there's always setting the environment variable directly 
in /etc/crontab.

There's also tricks like symlinks, bind-mounts, etc.

I'm sure Rubygems can be installed wherever you like -- but you really should 
solve the problem of being able to set global environment variables.
