Hi, I am new to Ruby on Rails. I am excited about Feed parsing but when I install FeedZirra I am getting this error.

I use Windows 7 and Ruby 1.8.7.

Please help. Thanks in advance.

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

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