I am having trouble doing gem installs, and I am getting the following
message. Any ideas on what I should try to do.

Hello, if you read the exception carefully:
C:\Ruby19>gem install ruby-serialport
Building native extensions.  This could take a while...
ERROR:  Error installing ruby-serialport:
        ERROR: Failed to build gem native extension.

"You have to install development tools first"

Seem you don't have development tools installed in your environment.

If you got that version of Ruby from RubyInstaller project, please
download the DevKit (Development Kit) and the instructions from the
download page:

http://rubyinstaller.org/downloads
https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

Also, search the group/forum, this has been discussed in the past and
you might get pointers to where to look if you encounter other
problems with that particular gem.
