Thanks, that was helping, but as I was having troubles with rmagic and
windows, i decided to switch to linux

problem is, after i installed everything listed on
http://rmagick.rubyforge.org/install-linux.html, trought apt-get on debian,
once I try to run the gem, this is what I get:

*macaco@ig88:/devel/rtst$ sudo gem install rmagick -r
Building native extensions.  This could take a while...
ERROR:  While executing gem ... (Gem::Installer::ExtensionBuildError)
    ERROR: Failed to build gem native extension.

ruby extconf.rb install rmagick -r
extconf.rb:1:in `require': no such file to load -- mkmf (LoadError)
        from extconf.rb:1


Gem files will remain installed in /var/lib/gems/1.8/gems/rmagick-2.0.0 for
inspection.
Results logged to /var/lib/gems/1.8/gems/rmagick-2.0.0
/ext/RMagick/gem_make.out*

Any help?
