If that was the intention, that could have been outlined in the
instructions.

DevKit needs to be separated from Ruby, because it contains files that
could affect a normal functioning system like find.exe, It just need
to be installed so it gets added to the path during gem installation.

These gems are not the ones used by ruby-debug19, also, you can't
manually install them as they depend on an active internet connection
to download ruby source headers and be able to compile.

It is clear here that it didn't find the tools needed to compile the
extension because you didn't properly install the DevKit.

I did my best to provide you with links and instructions where to put
what and how to install it successfully, yet however you neglected
these instructions and as result still having problems.

Please do not compare your Visual Studio installation or whatever
between machines, I can bet you're not installing the exact same
version of Ruby, and beause you aren't, the results are not
comparable.

Also, please read what I said about the gem versions, the attempts to
install manually/locally and the real need for an active internet
connection.

Please, also read some of the tutorials in the RubyInstaller wiki:

http://github.com/oneclick/rubyinstaller/wiki/Tutorials

Pretty much lot of folks following these instructions had great
success installing Ruby and DevKit and lot of gems.
