Gem install: Failed to build gem native extension (can't find header files)

I am using Fedora 14 and I have MySQL and MySQL server 5.1.42 installed and running. Now I tried to do this as root user:
gem install mysql

But I get this error:

Building native extensions.  This could take a while...

ERROR:  Error installing mysql:

    ERROR: Failed to build gem native extension.



/usr/bin/ruby extconf.rb

mkmf.rb can't find header files for ruby at /usr/lib/ruby/ruby.h





Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.

Results logged to /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out


What's wrong here? In installed ruby 1.8.7. and the latest rubygems 1.3.7.
rubygems ruby mysql

yum -y install gcc mysql-devel ruby-devel rubygems

gem install -y mysql -- --with-mysql-config=/usr/bin/mysql_config

For Debian, and other distributions using Debian style packaging the ruby development headers are installed by:


sudo apt-get install ruby-dev

For Ubuntu the ruby development headers are installed by:


sudo apt-get install ruby-all-dev

If you are using a earlier version of ruby (such as 2.2), then you will need to run:


sudo apt-get install ruby2.2-dev
