How to install Libreoffice 5.2.3 on Redhat Enterprise Linux 5.9

Redhat enterprise linux 5.9 meets all the system requirements as per Libreoffice official website, but when installed and run, it says it requires higher version of GLIBC_2.7

Is there anyway to install Libreoffice latest version on redhat linux 5.9, if so, please give step by step instructions.

In fact, if the software says it requires higher version of GLIBC_2.7. I think the only solution is to have a more recent GLIBC_2.7. Well that’s really a problem. Because many software require GLIBC. And maybe somes are not compatible with the one LibreOffice 5.2.3 needs.
So there are not many solutions :
1·Migrate to a newer RHEL version.
2·Migrate to Fedora.
3·Run LibreOffice in a Virtual Environnement (I can’t help you for that option)
4·Run LO in a Virtual Machine on a recent distribution (VirtualBox + Fedora for exemple).

That’s all the solutions I’ve found. But maybe other solutions are possible.

Just for the sake of One application, do I need to change or upgrade my OS.
