The first problem is installation of the two versions. That means there are 2 versions of executables available - usually in /usr/bin. (Like corona shows). Plus, the necessary library versions must exist in /usr/lib.

The simple solutuion to the problem is to create 2 development boxes; you can create virtual RH installs sitting on top of an x86 box with virtual box software (free), for instance. Install the compiler you need, compile & link the code statically (statically only if the librarties do not exist on production boxes), and then push it to production.

However based on your question wording it sounds like you need some sysadmin help, first. Find out what you have installed.
