Here, they use Ruby, the enterprise version - is that what you mean by
RBENV or RVM? The next release of ruby? from RH? will be the 1.93 or some
such, and include all the stuff in the enterprise version.

Development tools on a production box are a very, VERY bad idea. I assume
you can build the ruby app on your development box, and then move it as a
package to test, then prod.

I've also seen an article or two about ruby not scaling up well. From my
experience here, the apps seem to be *very* fragile, and it reminds me of
python 10-12 years ago, where updating it one or two subreleases broke
everything that had been working, including system tools.

ObStmt: No, I don't like ruby.
