If you build and test the package on CentOS and it works, then you've 
built a package for CentOS.  There's no need to make it any more 
difficult than that.

All that changes when you move an RPM from one system to another is how 
packages are named when you have dependencies, and what tools are 
available.  That's why it's important to build and test on the 
deployment platform.  When it works, it's done.
