Option 1 is not viable. On a machine that has multiple developers using it what happens when developer A needs devel rpm version X while developer B needs devel version Y? They have to take turns? Also people doing development on the machine might not be system admins. Asking a system admin to keep installing (and uninstalling) devel packages is not going to work.
