I try to install the ruby building tool buildr with rubygems on Windows
When I type “gem install buildr” within the console I get following
Building native extensions. This could take a while…
ERROR: Error installing rjb:
ERROR: Failed to build gem native extension.
C:/Programme/ruby/bin/ruby.exe extconf.rb install rjb
checking for jni.h… no

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.

Gem files will remain installed in

I know that buildr needs native C extensions, but according to the
official buildr homepage
should be asked on which platform buildr should be installed and on
mswin32 buildr should come with precompiled dlls. But I wasn’t asked!
Even when I type “gem install buildr --platform mswin32” the same error
Is there anybody with experience in installing buildr on Windows?
Thank you for your help.
