I need to install 2 different versions of OpenSSL simultaneously. I am currently using Amazon EC2 with the Amazon 32-bit AMI, which currently runs OpenSSL 1.0.0a. I have an old piece of software that I need to run that requires OpenSSL.0.9.6. Unfortunately, from what I have learned, OpenSSL is not backwards-compatible so I will need to install both versions simultaneously. I have found an RPM that will work, however, I have no idea how to go about installing them simultaneously without breaking anything. Any information on this subject would be greatly appreciated.
