RVM does not know how to install 'libyaml-devel' on Fedora 19

[tim@localhost ~]$ rvm install 1.9.3
Searching for binary rubies, this might take some time.
No binary rubies available for: fedora/19/x86_64/ruby-1.9.3-p429.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
Installing requirements for fedora, might require sudo password.
There is no 'libyaml-devel' package available for installation and RVM does not know how to make that happen,
please tell us how to install 'libyaml-devel' on 'fedora-19' here: https://github.com/wayneeseguin/rvm/issues

The solution is quite simple:
[tim@localhost ~]$ sudo yum install libyaml-devel
