Error when installing gem

[syedpenrose]

Hello,
I'm trying to install gem on windows 8, with rails configured. When trying to install via bundler, I'm getting the following error:
$ gem install summarize
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing summarize:
ERROR: Failed to build gem native extension.

compilation terminated.
make: *** [article.o] Error 1

Gem files will remain installed in c:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/summarize-1.0.3 for inspection.

Any suggestions?

Thank you,

I do have Dev Kit installed, if that helps.

you need to install the glib c library.

if you have homebrew, all you need to do is this:

brew install glib

I'm actually on Windows. Would I need Dev or Compiled version of glib? I tried with Dev and put the path in windows Environment Variables. Doesn't seems to take it.

Thank you,
