Hi guys,

Ive been trying to install the gem, ruby-serialport but having troubles  
with it on windows. I have installed the Devkit but no luck with  
installing the serialport. I have seen a few people having similar  
problems but haven't found a solution.

C:\Ruby192\bin\>gem install ruby-serialport  
Temporarily enhancing PATH to include DevKit...  
Building native extensions. This could take a while...  
ERROR: Error installing ruby-serialport:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ERROR: Failed to build gem native extension.

\*\*\* extconf.rb failed \*\*\*  
Could not create Makefile due to some reason, probably lack of  
necessary libraries and/or headers. Check the mkmf.log file for more  
details. You may need configuration options.

Gem files will remain installed in  
C:/Ruby192/lib/ruby/gems/1.9.1/gems/ruby-serialport-0.7.0 for  
inspection.  
Results logged to  
C:/Ruby192/lib/ruby/gems/1.9.1/gems/ruby-serialport-0.7.0/ext/gem\_make.out

Help will be much appreciated!! Thanks
