Type whereis gem and see if your symlinks were setup properly. If not,
you need to type:

sudo ln -s /home/user/bin/gem1.8 /usr/local/bin/gem

… and substitute the path for path where your gem1.8 file is located
and to the /usr/local/ file.

If your symlinks are all setup and you are able to sudo gem -v then
ignore the above. It will then just be a matter for you to set the
require ‘rubygems’ in your ruby scripts.

Place require ‘rubygems’ at the top of your scripts that require gems.

Did you try adding /home/usr/ruby to ruby’s search path
eg

ruby -I/home/user/ruby script/console

If that works then you can get ruby to automatically add that for you
by setting the RUBYOPT environment variable to “-I/home/user/ruby”

Assuming that you mean they install gems (the packages, not the
package manager rubygems) in /home/user/gems, take a look at this
article on setting GEM_HOME:
