Rubygems. A newly installed gem isn't added to $LOAD
I installed the new stable Ruby release and when I began to install gems I found out that the paths to them isn't added to the Ruby load path after successful installation of the gems.
What is the reason of this issue? How can I achieve it?
Thanks.
Here's my environment:
$ lsb_release -d
Description: Debian GNU/Linux 5.0.6 (lenny)
$ cat ~/.gemrc
gem: --no-ri --no-rdoc gemhome: /home/<username>/.gem gempath: - /home/<username>/.gem
$ gem environment

$ gem list
*** LOCAL GEMS *** rack (1.2.1) sqlite3-ruby (1.3.1)
$ ruby -e "puts $:"
# There's neither /home/<username>/.gem/gems/rack-1.2.1/lib # nor home/<username>/.gem/gems/sqlite3-ruby-1.3.1/lib here. /usr/local/lib/ruby/site_ruby/1.9.1 /usr/local/lib/ruby/site_ruby/1.9.1/i686-linux /usr/local/lib/ruby/site_ruby /usr/local/lib/ruby/vendor_ruby/1.9.1 /usr/local/lib/ruby/vendor_ruby/1.9.1/i686-linux /usr/local/lib/ruby/vendor_ruby /usr/local/lib/ruby/1.9.1 /usr/local/lib/ruby/1.9.1/i686-linux
Updated
I can't require any of the installed gems because they arn't in $:.
$ ruby -e "require 'rack'; puts $:"
:29:in `require': no such file to load -- rack (LoadError)
from :29:in `require'
from -e:1:in `'
But.
$ ruby -e "$: << '/home/<username>/.gem/gems/rack-1.2.1/lib'; require 'rack'; puts $:"
/usr/local/lib/ruby/site_ruby/1.9.1 /usr/local/lib/ruby/site_ruby/1.9.1/i686-linux /usr/local/lib/ruby/site_ruby /usr/local/lib/ruby/vendor_ruby/1.9.1 /usr/local/lib/ruby/vendor_ruby/1.9.1/i686-linux /usr/local/lib/ruby/vendor_ruby /usr/local/lib/ruby/1.9.1 /usr/local/lib/ruby/1.9.1/i686-linux /home/<username>/.gem/gems/rack-1.2.1/lib # Here it is!
It works that way only : (

ruby -e '

'
# Before require: []

things have changed for 1.9.2
http://wiki.github.com/rdp/ruby_tutorials_core/ruby-talk-faq#gem_loading_fails_191
it basically auto loads rubygems for you now, instead of pre-populating the load path.
