Not that I'm anywhere near an expert in ruby matters, but I have some (bad) 
experience with alternatives, so:

If this means running different individual applications with different 
stacks/stack versions, I strongly suggest reconsidering using the alternatives 
system for that.  Alternatives is for (easily) changing the system default 
stack, not at all for changing per-application ones.  And getting it right is 
not an easy task.  FWIW in fact I'd recommend not doing any alternatives stuff 
unless there are very strong, valid reasons for doing so.  We have an example 
with the current Java alternatives system in Fedora which in my opinion no 
longer has any real benefits but rather has a negative net effect and it'd be 
good to start planning for getting rid of it altogether.

On the other hand, if I got your intent right, environment-modules might be 
something to look into here.
