The MySQL driver apparently requires compilation of the native bindings.  
Do  
you have a C compiler installed on your machine and the environment  
variables  
properly setup for the MySQL includes and libraries?

And if you want to answer “Huh?” to the above paragraph, either use a  
win32  
gem if one’s available, ask the people maintaining the driver to make  
one,  
use Cygwin for development, or switch to Postgres which already has  
prebuilt  
mswin32 Ruby bindings available. Oh, and it also owns MySQL
