When i went to installation ferret in my rails application then i have
faced a problem that is look like this
ERROR: While executing gem … (Gem::FilePermissionError)
You don’t have write permissions into the /var/lib/gems/1.8
directory.
i used this command for ferret install
sudo gem install ferret
If you have any preference in using a search engine for your site, I
would recommend ultrasphinx, much more stable than ferret.

You don’t have enough info here to really help you. what platform,
etc… Check to see who the dir belongs to ‘ls -l’
Can you install any other gems?
