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

now I am trying

 gem install -v=2.9.0 rmagick --platform=ruby -- --with-opt-lib=C:/ImageMagick/6.6.7-Q16/lib --with-opt-include=C:/ImageMagick/6.6.7-Q16/include

Did not work for me, see

 http://groups.google.com/group/rubyinstaller/browse_thread/thread/c29da64804d0ee4a

but this did work for me

 http://rubyforge.org/frs/download.php/64917/RMagick-2.12.0-ImageMagick-6.5.6-8-Q8.zip

then do

 gem install gem install rmagick-2.12.0-x86-mswin32.gem

that results in

 CORE_RL_magick_.dll nicht gefunden.

set the correct PATH
