According to the document at project's
homepage(http://ruby-serialport.rubyforge.org/)

"It support POSIX (Linux, *BSD, Solaris, AIX, Mac OS X), Cygwin and
native Windows. The native Windows version of this library supports
Microsoft‘s Visual C++ and Borland‘s C++ compilers."

You cannot build and install ruby-serialport with MinGW Development Kit.
And even worse, the current ruby-serialport 0.7.0 is not compatible
with Ruby 1.9.x

There is another patched
ruby-serialport(http://github.com/hparra/ruby-serialport)
And you can install it like this

gem install serialport
