Whoops...forgot to mention.. I do have (various version) of Visual 
Studio loaded - VS 6, VS 2003, VS 2005, VS 2008. I've tried with each 
versions of VSVARS32.bat, which sets the env vars for the various 
environments.

This is the error, for eventmachine, after running the VSVARS32.bat:

ERROR:  While executing gem ... (Gem::Installer::ExtensionBuildError)
    ERROR: Failed to build gem native extension.
