xojo web on CentOS 6 64-bit

I’m trying to install Xojo on a CentOS 6.6 x86_64 (64 bit installation)
A lot of things do work but others don’t. I suppose I have to install 32-bit libraries.
On xojo-site we can read something about ubuntu.
But what should I install on CentOS 6.6?

Thanks for help

/usr/bin/yum -y install glib2.i686 libgcc.i686 libstdc++.i686
