To have a development on linux, i decide to install a Centos 7 on VirtualBox 4.3.8 on my Mac. It sound easy, usually it is ... but i don't know why this time have have a lot of issue.

So first i have to disable the Update repository that introduce wrong dependency that disallow me to install Gnome for example. To do that I edit the file /etc/yum.repo.d/CentosOS-Base.repo and at the end of the bloc updates i add enabled=0.

After that i have to install few stuff to have my development environment working.
