</div></div>Perhaps we can make something like rvm (or the more recent rbenv - which<br>
does seem simpler and more robust) central to the Fedora ruby strategy.<br>
They allow you to install multiple ruby versions with multiple gem<br>
stacks concurrently, and decide on a per-application basis what ruby<br>
stack to use. It would be good it if it was easy for Fedora users to<br>
install rvm/rbenv and multiple versions of ruby and rails via rpm and<br>
have it all work out of the box.<br>
<br>
On the other hand, it may be worth going to great lengths to ensure we<br>
have a single well-supported stack in that works with all the ruby<br>
applications we package for Fedora. Perhaps we need to make one official<br>
Fedora-supported stack and meanwhile make it as easy as possible to<br>
install additional ruby versions + gemstacks concurrently, say, from<br>
third party repos.<br>
