I’m trying to upgrade an old gem installation (0.9.5) on Debian machine.
On Debian, the default gem repository is /var/lib/gems/1.8. However, if
I install gem from source, the default location of the repository would
be /usr/lib/ruby/gems/1.8/. I can export GEM_HOME variable to change the
location however, this will not work for crontab scripts which bypass
.bash_profile and /etc/profile. There are many crontab scripts setup by
our users and it’s quite hard to force everyone to change their scripts.
Therefore, I need to make sure that the default gem repository is
/var/lib/gems/1.8. How do I force gem installation to do this instead of
