Following answers on this website (like: How to use TeX Live on Fedora 17? and Manually installed TexLive on Fedora 16 )
I installed texlive manually on fedora and it works flawlessly.

The problem I have is that tex is a requisite for other packages (such as R). Whenever I try to install (through yum) R i am required to install another tex  from fedora.
 I don't want to do so because the package is old, it doesn't have tlmgr and I don't want to have two installed tex.

Is there a way to make the OS notice I already have tex installed and the dependency is satisfied? 
Thanks!
