No such file to load -- thread (LoadError)

Hi All,

I removed all my rails and then ruby installation using sudo apt-get
remove and by deleting all gem and ruby folder manually.

Then I installed ruby. And tried to install gem(1.3.5 and1.3.6 also)
ruby setup.rb

I got following error

./lib/rubygems.rb:9:in require': no such file to load -- thread (LoadError) from ./lib/rubygems.rb:9 from setup.rb:24:inrequire’
from setup.rb:24

I am trying to resolve it but I not found any thing
