BioLinux-BR Project offers RPM packages for such popular programs as MolMol, PROCHECK and XPLOR-NIH.
Project description from its website:
BioLinux-BR is a project directed to the scientific community. Our intention is to create a Linux distribution for people with little familiarity with the installation of the operational system and mainly for people that do not know how they must proceed to unpack a program, compile and install it correctly.
For these reasons, we are giving our contribution, developing a Linux system that aims to be easy to use and still offering packages that will be part of the BioLinux-BR. Giving this option, we will not be compelling anybody to change its Linux distribution, since there are packages developed for the greaters Linux distributions.
We hope that our work be useful and benefical for you!
