While not as commonly seen as RedHat, Oracle Linux is a viable option and features the same package manager. While the package manager tools are the same as redhat, the pre-installed packages may not be. I was able to have a straight forward installation without any problems by installing these three packages in preparation, using these commands:
yum install unzip
yum install glibc.i686
yum install perl
You will need "unzip" for unpacking the zip file which contains prognosis, and both perl and glibc which are relied upon by the actual installer. While perl and unzip are commonly used tools, they are not always present.
