how to create gem

hi friends,
i need help on creating a gem. Am following the Dr. Nic tutorial

i started with installation of the new gem

step 1)---> gem install newgem

step 2)---> newgem <gem name>
here it creates the folder successfully with the name i gave, n it
allows the manipulation which is required by me.

here comes my problem???
step 3)—> rake package
while creating a gem with the "rake package command", I came across an
error saying "could'nt find HOME environment --expanding '~/hoerc'"
which is followed by number of error lines…

c:/ruby/lib/ruby/gems/1.8/gems/hoe-1.4.0/lib/hoe.rb:327:in 'expand_path'
c:/ruby/lib/ruby/gems/1.8/gems/hoe-1.4.0/lib/hoe.rb:327:in 'with_config'
c:/ruby/lib/ruby/gems/1.8/gems/hoe-1.4.0/lib/hoe.rb:322:in 'initialize'
./config/hoe.rb:50:in 'new'

please tell me where iam going wrong!!!!!!!!!!!!!!!!!
