I have just pushed binary rubies installation support, this will be released shortly (week or two) with RVM 1.16.0.

You can test it using: rvm get head && rvm reload rvm install 1.9.3 --binary || rvm help install

Please let me know if rubies are not available for some commonly used platform - only ruby 1.9.2+ can be compiled for this and on systems with /usr/lib64 only 1.9.3-p125+.

If you find any problems with binary rubies (or RVM) you can report them at the rvm issue tracker or discuss them directly with me(mpapis) on #rvm on irc.freenode.net.
