Update environment on regression machines

I installed ant 1.7.0, ruby 1.8.6 and rake 0.7.3 on excalibur.

One observation was that installing rake was that for me at least (not ever having used ruby before), installing rake was not exactly idiot proof. It took about 15 minutes and several googles to figure out what other random pieces of ruby code I needed to install beyond just ruby and rake. I'm still not 100% sure the installation is correct (I ran the rake test suite and it didn't get a clean pass...results appended).

As long as we're just thinking about rake for using mainly on the regression machines and by core team members for doing heavy testing I think this is ok. We can afford the overhead of helping a few people install this stuff on their machines. f we're going to get to a point where we think "normal" users are going to need to have rake installed, then we're going to have to put some effort into documenting exactly what they need to install (in very precise detail).

The idea is to eventually require ruby/rake for all testing so may need to look at documenting/streamlining the install. However it should be relatively easy for most systems. Basically you need ruby+ruby gems installed which is something like "emerge dev-ruby/rubygems" gentoo systems. Ubuntu has a similar step and win32 and OSX have installers that you run (Sorry no idea about aix :]).

Then to install rake it is something like

gem install rake --include-dependencies --http-proxy=http://proxy.foo.com:8080

I will wiki it when the time comes.

Dropping priority on this under the theory that it isn't really a blocker. If it is a blocker, then we should resolve by updating ANU machines.

I think this is out of date.
