Subject: How to add a non standard Gem path?

Hi, I would like to install some Gems in a custom directory (i.e.
/usr/local/gems/), so such a directory will have the following
structure:

  ibc@myhost: /usr/local/gems$ ls -l

  drwxr-xr-x 2 root root 4,0K ago 29 18:02 bin/
  drwxr-xr-x 2 root root 4,0K ago 29 18:01 cache/
  drwxr-xr-x 2 root root 4,0K ago 29 18:01 doc/
  drwxr-xr-x 6 root root 4,0K ago 29 18:01 gems/
  drwxr-xr-x 2 root root 4,0K ago 29 18:02 specifications/


Once I've started a Ruby script, how can I tell the "require" command
to include my custom Gem directory so "require GEM_NAME" command looks
first in /usr/local/gems/gems/*/lib/* ?


I've tryed modifying the Gem.path which by default has this value:

  Gem.path
  =>  [ "/var/lib/gems/1.9.1", "/home/ibc/.gem/ruby/1.9.1"]

so I've added my directory:

  Gem.path.insert 0, "/usr/local/gems"
  Gem.path
  => ["/tmp/gems", "/var/lib/gems/1.9.1", "/home/ibc/.gem/ruby/1.9.1"]

But this does not work, "require" command does not search there.



Any help please?

Thanks a lot.
