Gems installed to $HOME not recognized

I’m using Ruby 1.9, Ubuntu (I don’t have the following problem with my
Ruby 1.8).

For some reason, Ruby 1.9 doesn’t see gems I install to $HOME. It only

when I do ‘require “haml”’ ruby says there’s no such file to load.

$ sudo gem1.9.1 install haml

…the gem gets installed in /var/lib/gems/1.9.1/gems/haml-2.2.22, and
doing ‘require “haml”’ works.

and gems then followed the installation instructions for rvm using the

Hope it helps you!

I had the same problem on Ubuntu 9.10. Setting the environment
variable GEM_HOME to the location of my gems seems to work.
