git-rails init can't find HOME environment

I'm trying to teach myself version control using GIT on a Windows
machine for my ROR development. I downloaded and ran the cygwin and it
created the following files:
'./.bashrc' -> '/home/Wayne//.bashrc'
'./.bach_profile' -> '/home/Wayne//.bash_profile'
'./.inputrc' -> '/home/Wayne//.inputrc'

Wayne@Gateway ~
$

I also installed the gem git-rails

I've created a project and did a cd to that project.

Now when I run get-rails init I receive what looks like an error
finding my HOME path as follows:

                C:/ruby/lib/ruby/gems/1.8/gems/git-rails-0.2.1/bin/git-
rails:12:in `expand_path': couldn't find HOME environment --
expanding `~' (ArgumentError)
  from C:/ruby/lib/ruby/gems/1.8/gems/git-rails-0.2.1/bin/git-rails:12
  from C:/ruby/bin/git-rails:19:in `load'
  from C:/ruby/bin/git-rails:19

Any ideas?

And another thing...

To permanently set an environment variable for bash, set the environment
variable in the .bash_profile file:

HOME="/home/Wayne"

You might also want to add a comment to any change you make to
.bash_profile, so that in the future you will know why you made the
change that you did. Comments are preceded by: #

Spaces are not superfluous, so write the assignment exactly as written
above.
