Problem installing gem pauldix-feedzirra on windows

I am trying to install pauldix-feedzirra gem on windows xp and getting error like this :

Building native extensions. This could take a while... ERROR: Error installing pauldix-feedzirra: ERROR: Failed to build gem native extension.

C:/InstantRails-2.0-win/ruby/bin/ruby.exe extconf.rb checking for curl-config... no checking for main() in curl.lib... no * extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --srcdir=. --curdir --ruby=C:/InstantRails-2.0-win/ruby/bin/ruby --with-curl-dir --without-curl-dir --with-curl-include --without-curl-include=${curl-dir}/include --with-curl-lib --without-curl-lib=${curl-dir}/lib --with-curllib --without-curllib extconf.rb:12: Can't find libcurl or curl/curl.h (RuntimeError)

Try passing --with-curl-dir or --with-curl-lib and --with-curl-include options to extconf.
