What is ruby(abi) or rubyabi?

Hola,
I have problem to install a RPM.

RPM install error: Transaction check failed: ruby(abi) = %{rubyabi} is
needed by rubygem-inifile…rpm

My Centos is 6.6, I use RVM to install ruby 1.9.3p551 (2014-11-13
revision 48407) [x86_64-linux].

I find Fedora 19 changed how Ruby requirements are specified. This is a dummy package to ease the transition of Fedora 18 => Fedora 19 third-party packages. · GitHub to solve this. But I use
RVM, no RPM can find ruby1.9.3 installed.
Can you help, yes?

Gracias,
