To install gems that depends on binary extension, like yours, you need
a compiler.

Ruby needs a version specific compiler, the same used to build Ruby,
which is Visual C 6.0

Unless you have a license, that compiler is not available.

I suggest you play with or try out the preview version of the new One-
Click Installer based on GCC, let you build gems with native
extensions without these issues.

Keep in mind that certain gems may not work, and headers and libraries
to build certain gems are required to successfully build them.
